## DØ Collaboration meeting  October 13, 2000

**News**
**Status for Run II**
**Announcements **

- SUMMARY

## News I

- ACAT 2000,  Oct 16-20.

- Still subsidized registration available for students & postdocs:  contact Pushpa Bhat (bhat@fnal.gov)

- Shifts before March 1, 2001

- Office space

- Complete  new building  ~june 2001
- Conference room, where ? DAB, new bldg
- Until then:  *severe squeeze, starting now*

- Started with shifts
- Sign up is in place
- Need for people is increasing
- NEED more PEOPLE TO SIGN UP

- Tevatron working groups ( a la LEP)

- Joint letter from CDF & DØ to directorate, urging to start Tevatron working groups

- Not the first attempt
- Both CDF & DØ would like to do this
- Had another meeting with Shaevitz
- Do it before Run  II starts and it seems like we have to do it ourselves.......

## News II

- Strong Authentication for logon to DØ systems

- Publications

- Today Oct 13, 2000 DØ submitted the 100th paper

- See talks by M.Crawford and W.Merritt
- Pay attention to D0news, email etc warning of upcoming deadlines.
- Avoid delays due to this.

- (89 publish, 2 Accept, 9 submit)

- Budget for this year (FY01)

- Budget for next year is now clear
- Despite continuing resolution do not expect an impact on start of Run II
- Of course operating & visitor budget less than we like

- This was a major concern in August and September

- Forward funding

- Forward funding from SUNYSB, MSU, NIU and ND saved us in FY00 ( $2.2M)

- Thank you !!

## News III

- Schedule

- BD is bringing up Tevatron:  Commisioning run
- 1x8 stores have happened
- CDF is in beam with incomplete detector
- DØ has luminosity monitors, radiation monitors + FPD parts in beam ( with results)
- Nominal end of the run is Nov. 1, but want to establish 36x36 bunch operation
- Any delay in Nov 1 at most a few days
- DØ :  collision wall down on Nov. 1
- DØ :  any delay in Nov. 1 date  is a delay in March 1 readiness

## FPD Status     

-  Antiproton side Dipole and Proton side Quadrupole castles  installed in the tunnel
-   Dipole spectrometers have full scale detectors;  some Quadrupole pots have trigger scintillators

-  Good progress on Software front
-    Tracking in C++ (1st version)
-    DPGeant implemented in d0gstar
-    MI studies using LM finished
-    POMPYT interface to d0gstar underway

-  Several tests being performed using online interface (Rack Monitor) for control/monitor
- First pot insertion rate planned for 10/13
- Possibly some data taking next week

- Part of Run II detector where funding is still unclear, but large contributions from institutions.

## Detector Installation

_**Detector Installation**_

## Status I

**List of milestones in recent DØ history; part 1**

- Fiber tracker installed & south side is cabled
- Crysostat + VLPC’s operational
- LED induced signals observed in fiber tracker;  noise performance good
- Detector in final position for roll in (BIG pieces are in place)
- SMT progressing well (slips in time, but making it);  SMT-S ready soon
- 10% test give confidence on performance of SMT
- Lab F forward muon assembly complete; installation is ongoing
- A lot of work on infrastructure in hall
- One production line left:  VLPC cassettes:  difficult & building for long life.
**No fallback options have been initiated (most likely none will be)**

## Status II

- Detectors will be at DØ in time for March 1, 2001
- However readout electronics are late.  ==
- No integrated cosmic ray commissioning of detector before March 1;  partial yes
-  integrated & complete commissioning difficult
- Unless the “March 1” strategy changes, we will start the run with a mechanically complete, but electronically incomplete detector.
- Start discussions about this with directorate next week;  how to approach this.

**There are 139 days left to March 1, 2001**

**Status II**

## Status III

- Several offsite MC production centers are online
- Producing MC events at a very high rate
- Capabilities are expending

- For Run I Mcphysics (1990): produce 100K events in 6 months
- For Run II in 6 months produce (now only):
- 180 Million events. **Will double soon.**

- CPU power so large that there is talk of not saving intermediate data, but if needed....... just regenerate

- Current centers:

| Location  | # CPU’s |
| --- | --- |
| NIKHEF | 100 |
| UTA | 50 |
| Lyon  | 100 |
| Boston Univ. | O2000 (192) |
| Prague | ~15 |
| Lancaster | 200 |
| Rio  | proposal  |

- ~10**6**
- evts/day

- soon

- To set he scale:

*---Excellent for physics in Run II---*

**Status III**

## Announcements

- Nov 3-5, FNAL PAC;  present Run IIb plans
- Nov 10-11, Run II Top Thinkshop
- Dec 8 , Run II mtg & DØ Top/Higgs workshop

- 2001 dates

- Future DØ meetings for 2001 (DRAFT)

- Joint CDF & DØ workshop on Monte Carlo’s (generators)

**Announcements**

- February 7-9
- April 25-27
- June/July workshop*
- September 12-14
- November  7-9

- * Try wrkshp in Chicago area (not FNAL)

- G.Brooijmans, S.Protopopescu

- Will try to move to collaboration week style meetings

## Closing remarks

- Progress has been immense over last year and continues
- Not mentioned Run 2B:  a lot of discussion, converging on finite number of options;  resources are main concern
- (bad timing but.....have to deal with it)
- Detectors are nearing completion;  shift from priority on hardware to commissioning and software  people available
- A lot of activity in assembly hall;  next few months even scary
- However I can  see the beginning of Run 2a
