2. 2Malcolm Ellis - Video Conference - 7th December 2006 Disclaimer  I am starting my Christmas holidays early this year so Paul has agreed to give this presentation.  Please don’t shoot the messenger!  Questions or suggestions can always be sent via email, or better yet, in person at software phone meetings or workshops (hint, hint...)  Next Software Phone Meeting is in the new year, will be announced as usual on the mice-software list.

3. 3Malcolm Ellis - Video Conference - 7th December 2006 Data Challenge Definitions  Software Group: u A test of the capabilities of the software tools to perform the tasks (“Use Cases”) that the Analysis group (and MICE in general) require. u Attempting to do a moderately large scale production of simulated data including a realistic analysis is a useful way of checking that the tools we have work the way they should and that we have all the tools that we need.  Analysis Group: u Choosing the correct simulations can mean that the results don’t just test the tools, but produce physics information of immediate interest. u Suggested study – can MICE demonstrate to sufficient precision: s Transverse Cooling s Re-acceleration s Acceptable longitudinal emittance growth s Analysis technique does not require substantive MC corrections

4. 4Malcolm Ellis - Video Conference - 7th December 2006 Suggested Simulations  Would like to have a better understanding of how to: u Select an input beam u Phasing of the beam wrt the RF cavities  Suggested settings: Baseline 200MeV/c, beta=42 case, Step VI: For: Empty channel = no H2, no RF Full channel = H2, RF 'on crest' For: No Diffuser Diffuser to give ~10(pi)mm beam  Conditions: u Best (current) 200 MeV/c beam line design starting upstream of TOF1 u Time distribution of muons flat wrt RF phase. u Zero crossing time of RF recorded in a manner similar to the real experiment (e.g. TDC used in TOF readout).

5. 5Malcolm Ellis - Video Conference - 7th December 2006 More options  KEK Analysis – we have multiple configurations to study: u Low medium and high momentum. u Magnetic field on and off. u Magnet at different angles.  Would like to use the tools developed in the Data Challenge to simulate the different KEK configurations and analyse the real data.  This will likely happen as a second pass.  One of the Stage 6 settings on the previous slide will be selected for the first tests of the system.

6. 6Malcolm Ellis - Video Conference - 7th December 2006 G4MICE Status  Just released a new tag: mice-1-9-3 (email sent to mice-software).  Many fixes and new features: u Introduction of a memory monitoring facility to all of the major classes to allow for testing of memory leaks. u Addition of memory use checks to the existing and new tests. u Fixed a number of leaks in the TextFileIo persistency. u New pattern recognition in the SciFi for the no field case. u Working version of the Imperial decoding for the SciFi. u Fixed data files for the Imperial decoding. u Added tests of both SciFi decoding schemes. u Preparations for more advanced visualisation of simulated and reconstructed tracks. u A new application to generate matched beam distributions of a desired momentum and emittance. u An Application to perform the alignment of the SciFi tracker using the KEK test beam data. u A production application to perform the analysis of the light yield of the prototype tracker from data taken at KEK. u An example application to show how to use the ZustandVektor for analysis (e.g. tracker resolution, station spacing optimisation, etc). u Additional KEK test beam models (field off and field on, using a calculated field map from the solenoid currents). u Two new Reconstruction unit tests to serve as examples for the development of the remaining tests needed for the full reconstruction release.  Now have 62 tests, still insufficient coverage, but moving in the right direction

7. 7Malcolm Ellis - Video Conference - 7th December 2006 GRID Status  Had been stalled for quite a while (limited effort, lots of other tasks).  I have a new GRID certificate (DOE GRID) and have joined the MICE VO.  For a while this was causing problems with the Imperial Portal, however that was fixed yesterday and in January we will start running the first test jobs on the GRID using the MICE VO for the first time.  I’m only aware of one or two people in MICE who have a GRID certificate and who are on the MICE VO!  Please get a (free) certificate and join the VO (contact me for help with the latter)  Or buy yourself lots of expensive Linux PCs....  The software group will provide the tools, but the 2-3 FTE of us that are left will not be running all of the simulation and analysis jobs!

8. 8Malcolm Ellis - Video Conference - 7th December 2006 Next Steps  Collect a firm set of settings from Analysis and Tracker groups and make a prioritised list.  Prepare scripts for GRID jobs and run small test jobs to debug them.  Release mice-2-0 (Simulation and GRID production tools).  Run Data Challenge Simulations and analyses of simulated results.  In parallel: u Write Reconstruction tests to validate all aspects of track finding and fitting. u Prepare for migration to new version of RecPack (Kalman fitting package). u Update documentation in preparation for TB review.

9. 9Malcolm Ellis - Video Conference - 7th December 2006 Aspired Schedule  December – work on Reconstruction tests to pave the way for a Reconstruction release with fully working track fit and extrapolation under the new design with B field or no field.  January, week 2 – first test jobs on the GRID  January, week 3 – converge on tag for Simulation and configurations, beams, statistics for first production  January, week 4 – start production  February, up until CM – production and analysis of first results (as well as preparation for TB review).

10. 10Malcolm Ellis - Video Conference - 7th December 2006 Software Workshops  Proposed schedule (to mice-software list) has not resulted in many responses.  Please look at the schedule below and let me know how many of these you may be able to attend and in any cases if a small change in date would make attendance more likely.  First workshop is set now, others will be confirmed in early January. u 22 nd – 24 th JanuaryFermilab u 28 th February – 2 nd MarchBrunel (or RAL) u 9 th – 11 th AprilFermilab u 6 th – 8 th JuneRAL (just before CM) u 6 th – 8 th AugustFermilab u 3 rd – 5 th OctoberRAL (just before CM)
