## Recent History of Fsec ID project 

**Recent History of Fsec ID project **

**	****	****	****- SXR undulator project**
**	****	****	****	****	****- proposed as an in-house project to build a ‘low cost’ system using a borrowed ID**
**	****	****	****	****	****	****	****- stalled BL 6 proposal at DOE and problems on 5.3.1 bend magnet BL**
**	****	****	****	****	****- optical scattering**
**	****	****	****	****	****	****	****- significant effort directed at understanding 2d scattering problem (partially solved)**
**	****	****	****	****	****	****	****- detailed measurements of profile on 5.3.1, 10.3.2, 7.3.3, PX and attempts made to ****	****	****	****	****	****	****	****  correlate optical and x-ray measurements**
**	****	****	****	****	****	****	****- R&D contracts placed with Seso and InSynch to try to improve sag. roughness**
**	****	****	****	****	**
**	****	****	****	****	****- vertical dispersion**
**	****	****	****	****	****	****	****-  study shows practical route but effect on vertical emittance may be too big**
**	****	****	****	****	****	****	****-  experimental study about to start**
**	****	****	****	****	****	****	****-  study shows that increasing 5.3.1 dispersion causes significant decrease in lifetime**
**	****	****	****	****	****- energy modulation**
**	****	****	****	****	****	****	****- experimental studies show 8 MeV m=3 kick, and 14 MeV m=1 kick**
**	****	****	****	****	****	****	****- 8 MeV energy kick with standard dispersion too small for 5.3.1 expertiments**
**	****	****	****	****	****	****	****- confirmed by analytic and FEL simulations**
**	****	****	****	****	****	****	****- practical ‘saturation’ limited by non-linear optical effects in window (possibly)**

**Recent History of Fsec ID project**

**	****	****	****- SXR undulator project**
**	****	****	****	****	****- SXR beamline optical design completed **
**	****	****	****	****	****- BL mechanical system studied, based on MES, Rigaku chopper....**
**	****	****	****	****	****	****- initial 3d layout of beamline components completed**
**	****	****	****	****	****- angular slicing with modulator and radiator in 1 straight examined**
**	****	****	****	****	****	****- best time resolution, avoids mirror scattering, requires undulator operation (E> 300 eV ****	****	****	****	****	****	**** < 3 keV, m=>3), complex but doable straight 6 layout, in-situ mod to sector arc chamber, ****	****	****	****	****	****	****  change to shield wall door...**
**	****	****	****	****	****- recognized that practical operation will require an m=1 modulator**
**	****	****	****	****	****	****- permanent magnet and hybrid designs should work and give PX similar performance**
**	****	****	****	****	****	****	****- cost / schedule being assessed**
**	****	****	****	****	****	****	****- recognized that this is required for routine 5.3.1 experiments**
**	****	****	****	****	**

## Fsec ID project

**Fsec ID project**

**	****	****	****- Ultrafast X-ray Facility approved by DOE**
**	****	****	****	****	****- proposal called for 2.175, 3.401 and 1.410 M$ (total 6.986 M$) in 3 year construction**
**	****	****	****	****	****- 1.712 M$ in FE and ID costs to be provided by ALS**
**	****	****	****	****	****- proposal called for 1.5T, 3 cm s/c ID + combined soft and hard x-ray mono (E=0.1 - 10 keV)**
**	****	****	****	****	****	****- only solution identified is vertical position slicing, m=1 modulator in straight 5**
**	****	****	****	****	****- assuming the proposal model for funding profile, technical goals**
**	****	****	****	****	****	****- year 1 funding should be directed towards highest risk components**

**	**
**	****	****	****	****	****	****	****- combined and separated hard/soft BL design will be studied in yr 1**
**	****	****	****	****	****	****	****- studies of dispersion bump and optimizing energy kick will continue through yr 1**
**	****	****	****	****	****	****	****- studies of mirror scattering will continue through year 1**
**	****	****	****	****	****- project will entail significant ongoing R&D**
**	****	****	****	****	****	**** **

## Fsec  project group priorities

**Fsec  project group priorities**

**	****	****	****- Insertion devices**
**	****	****	****	****	****- finish strawman m=1 straight 5 modulator design (will enable 5.3.1 operation)**
**	****	****	****	****	****	****	****- 3d PPM / hybrid, chamber gaps/stress modelling....**
**	****	****	****	****	****- produce cost / schedule for in-house, commercial and mixed solutions**
**	****	****	****	****	****	****	****- preferred solution is to obtain complete system from commercial company**
**	****	****	****	****	****	****	****	****- will allow any in-house resources to be concentrated on s/c ID**
**	****	****	****	****	****	****	****- estimate  / schedule need for Shank immediately; all funding needed in FY03**
**	****	****	****	****	****	****	****- because routine operation on 5.3.1 cannot proceed without this device, this needs to ****	****	****	****	****	****	****	****  be #1 priority with a route identified to installation in 1 year**
**	****	****	****	****	****- strawman 11 cm device needs accelerator group to check on impact on machine operation**
**	****	****	****	****	****- 1.5 T, 3cm period s/c undulator**
**	****	****	****	****	****	****	****- some design started, LDRD funded for FY03**
**	****	****	****	****	****	****	****- check on Wang SRRC progress**
**	****	****	****	****	****	****	****- produce strawman project plan so we can estimate manpower / capital costs**
**	****	****	****	****	****	****	****	****- we need to know cost / manpower profile over the 3 years of the project**
**	****	****	****	****	****	****	****- LDRD will address critical R&D issues, eg. winding geometry, quench protection,**
**	****	****	****	****	****	****	****  ****cryogenics.....**
**	****	****	****	****	****	****	****- note: 1.2 M$ is in the budget; this may be a challenge!**
**	****	****	****	****	****	**** **
**	****	****	****	****	**

## Fsec project group priorities

**Fsec project group priorities**

**	****	****	****- Accelerator**
**	****	****	****	****	****- validate that 11 cm m=1 straight 5 modulator impact is no worse than W16 or is acceptable**
**	****	****	****	****	****- experimental test of 4 cm vertical dispersion in 6.0**
**	****	****	****	****	****- assess impact on vertical emittance of s/c ID and for a 2 straight dispersion bump the ****	****	****	****	****	****  effect of the 11 cm modulator in straight 5**
**	****	****	****	****	****- completion of current study on 5.3.1 dispersion bump**
**	****	****	****	****- Beamline**
**	****	****	****	****	****- plan for vertical beam separation**
**	****	****	****	****	****- study combined and separated hard - soft x-ray beamline(s)**
**	****	****	****	****	****- continue scattering theory / R&D**
**	****	****	****	****	****	****- is it possible to obtain a prototype mirror and test it as part of project**
**	****	****	****	****	****- produce project plan/cost estimate; assumption is that main mech. eng. will start in yr 2**
**	****	****	****	****	**** ****design chopper in year 1, order parts; yr 2 testing**
**	****	****	****	****	**** ****- continue work on ultrafast gated detectors**
**	****	****	****	****- Laser**
**	****	****	****	****	****- hire laser engineer**
**	****	****	****	****	****- detailed design and R&D testing of high power amplifier**
**	****	****	****	****	****- laser system is a high risk component; must be started in yr 1**
**	****	****	****	****	****- produce strawman cost and schedule**
**	****	****	****	****	**

## Fsec ID project

**Fsec ID project**

**	****	****	****- we must assume for now that DOE will fund the project over 3 years starting early in FY03**
**	****	****	****	****	****- this means that we must prepare a project plan now in preparation**
**	****	****	****	****	****- all groups (accelerator, laser, beamline, ID) need to prepare a cost/schedule estimate**
**	****	****	****	****	****	****	****- assume that laser, s/c undulator projects start in yr 1 to be completed in the 3 year ****	****	****	****	****	****	****	****  project schedule, BL starts in year 2, modulator is finished in year 1, chopper is built ****	****	****	****	****	****	****	****  in year 1, tested in year 2**
**	****	****	****	****	****	****	****- note: project proposed spend profile is for 2.175 M$ in year 1; this may be difficult as**
**	****	****	****	****	****	****	****  ****significant R&D needs to be done before major spend on laser and s/c ID**
**	****	****	****	****	****	****	****- we should attempt a zeroth order cost / plan in 1 month**
**	****	****	****	****	****- Bob Schoenlein will generate a baseline set of technical parameters**
**	****	****	****	****	****	****	****- nominal dispersion, energy kick, photon energy range etc.**
**	****	****	****	****	**

## Fsec ID project

**Fsec ID project**

**	****	****	****- things to worry about**
**	****	****	****	****	****- if DOE doesn’t declare the funding profile, what do we assume**
**	****	****	****	****	****- if DOE funds the project at a significantly reduced rate, do we change goals**
**	****	****	****	****	****- we have abandoned the 1.5 year SXR only option**
**	****	****	****	****	****	****- we have SLS and BESSY competition; will they beat us to the finish line?**
**	****	****	****	****	****- we don’t have a magnetism component to the proposal and this area may be one of the ****	****	****	****	****	****  most exciting (eg. it’s the only area BESSY are aiming at) and we are ruling out an ability ****	****	****	****	****	****  to do SXR magnetism experiments (on ferromagnets; we would need an EPU or ****	****	****	****	****	****	****	**** asymmetric wiggler)**
**	****	****	****	****	****- we are chosing a time resolution of 200 fsec wide energy bandwidth operation over**
**	****	****	****	****	****  ****300 - 3 keV SRX operation with 60 fsec time resolution and angular slicing; we don’t see a ****	****	****	****	****	**** need to focus on diffraction now, so the justification is K edge spectroscopy where you ****	****	****	****	****	**** need large penetration power (eg. dilute solution chemistry). Is this the best scientific ****	****	****	****	****	****	**** focus?**
