## LAr deliverables for release 14

## Main aim is increased robustness, dealing with possible problems and pathologies
Cosmics : M6 (13.2.0) and later global cosmics
FDR-2 : 
Physics calibration stream (can we re-run digitization with rel 14?)
Calibration algorithms to be run on express stream
First pp collisions
Also simulation to derived updated corrections for day 0

Most new infrastructure and developments related to fulfilling Data Preparation tasks
Some of the deliverables are also for code cleaning and maintenance

## Database

- Largest volume of conditions is in electronics calibration
- In place and exercised in commissioning (cf later). Need some small tuning of Cool channels definition.
- Cool+Pool based
- For rel14: T/P split of conditions data (already done for most complicated objects)
- Other existing conditions
- Identifier mapping, cluster level correction: same Cool+Pool, existing (mapping put in Cool for 13.1.0). No development planned on infrastructure

## Database (cn’td)

- New infrastructure to add in release 14
- Bad channel database: (cool inline)
- Interface in 13.1.0
- For 13.2.0: Cool backend + first client use (with preliminary list)
- Needed already for M6
- For 14: more clients, also propagate to combined reconstruction (?), updated list.
- Calorimeter conditions (noise, pedestal shifts) as derived from data
- Common solution agreed with Tile: Cool inline using same infrastructure as Tile calibrations, access with offline identifier
- Software for data object just written.
- Then should develop some algorithms: For FDR-2
- Common HV interface to use in simulation and reconstruction

## Detector Description

- For deriving new set of cluster calibrations from rel 14 simulation
- Refined description of barrel-endcap crack
- Done end of 2007, in new Lar geometry version
- Note documenting what has been put in written (M.Thioye)
- Would like some blessing from ID side
- Some improvements in end-cap geometry (HEC)
- Don’t expect significant effect on results, but cleaner and making also end-cap TB simulation support easier.
- Partially done
- Pear shape of barrel and sagging in EMEC don’t considered critical for rel 14
- Sagging in barrel already exists since rel 12 but never used in production

## Simulation

- No critical items on the software side but several possible small improvements (like Birk’s law, trying to improve CPU, ...)
- Simulation of TB setups working and maintained: OK for H8-CTB, mostly done for H6 (EndCap)
- Most important parameter is the proper choice of G4 parameters (version and physics list, also range cuts) which is driven by Test-Beam analysis: For simulation for first pp collisions

## Digitization

- Update MC conditions (noise, MeV/ADC conversion factors, ...) to be based on commissioning data rather than 2002 test-beams (or even older inputs for Fcal): For simulation
- Fcal numbers already in database (not used yet)
- Inputs for EM collected and ready to be put in database
- HEC to follow
- Mimic in MC digitization the logic to save ADC time samples for cell above threshold, as should be done online
- In progress
- For FDR-2 (?)
- First prototype of algorithm to overlay MC signal and random raw data
- Being worked on, few weeks time scale.
- Full implementation including proper database accesses probably in 15

## Reconstruction/EDM

- Reconstruction:
- Optimization of memory usage (use of float vs double,etc..)
- Work starting using dedicated MIG nightly (impact clients of Calo detector description for instance)
- Specific cosmics reconstruction case (for M6)  (number of OFC sets, ...)
- Complete migration to configurable.
- Merging for RecExCommon/RecExCommission
- Optimization of slidinw window clustering (EM clusters) (for first data)
- EDM:
- T/P split for LArDigits (done)
- Migration of LArRawChannelContainer and LArDigitContainer to simple std::vector (will also use MIG nightly, impact clients)
- Fine tuning of number of cells saved in AOD for EM clusters (for e/gamma)
- Mostly straightforward
- Same small extension of the software to also include cells in crack + first layer of EM calo
- Better solution for Jets -> Topocluster navigation in AOD
- Simple brute force solution ~available now
- Working on more elegant solution

## Cluster level calibration

- Use of “calibration hit” method as default for EM cluster correction
- Software already written for release 13 (but not applied by default)
- Some improvements being done (software + constants in Pool)
- Being checked before it is committed. Should be there in 13.2.0
- Hadronic calibration for TopoCluster
- No major development, improvements in dead material correction

## Electronics calibration processing

- Aim is to produce full set of calibration constants from calibration runs in O(1 hour) in Atlas conditions
- All database infrastructure + reconstruction algorithms exist since long time
- Automatic processing of a full set of calibration runs is now working. Should be the prototype for the futur Tier0 processing
- Missing layer is data quality of electronics calibration
- Comparison with values stored in database
- Dealing with bad channels also in automatic way
- Being sure that no “crazy” value is put in the database
- Main short term client is commissioning cosmics data taking

## Data Quality

- Developments of monitoring tools
- For M6:
- Use of bad channel tool
- Digits, cell and cluster level monitoring + DQMF output
- For express stream monitoring: Trigger aware monitoring

## Trigger software

## Conclusions: highest priority items

- Database infrastructure developments
- Bad channel tool for cosmics: being actively working on
- Would like to exercise new structures related to calibration done on express stream with FDR-2
- All tools for processing + data quality of electronics calibration constants
- These constants will be used online for data taking
- Things related to algorithm “tuning” are probably easier to do in 14.0.X branch
