bullet- Richard and Leon: GLAST release tomorrow.  New package: analysis tuple, which contains Bill's new tuple information (with help from Leon and Toby to implement the new package).   The names of the tuple variables are about to change, so stay tuned.  This needs to be documented.   Built a CAL recon tool to call Bill's energy recon.  Ready to run new batch of background events.  Bill, Steve, and Richard will propose a first set of standard runs to support consistency across studies.
bullet- RIchard on Windows compilers: will announce 2 dates: (a) the date after which it is recommended we start migrating to .NET; (b) date after which V6 will no longer be supported. 
bullet- Leon: calibration database progress.  Just about done: TKR bad strips, with a root macro to produce the files.  TOT is next.
bullet- Bill: stopped development on CAL energies (close enough for now).  Replugged the new CAL energies back into PSF and background analysis.  PSF tails back up, due to use of actual energies -- working on this.  NEED TO GET XML VERSION OF TREE PREDICTORS INTO C++ .  Toby was working on this -- must have an automatic way to do this.  Report at a future meeting.
bullet- Berrie: will report at the next meeting.
bullet- Hiro: alignment studies moving forward.  Expect results by the end of the month.
bullet- Dave and Steve: ground-level muon studies, using flux being implemented by Toby.  Also continuing to work on understanding the residual differences in TKR trigger rates relative to pdrApp.
bullet- Julie: lots of discussion about the experience of Linux users.  Our "standard" packages of G4 and Gaudi are barely compatible to run in a single compiler.  Lack of ANSI standard coding practices in Gaudi currently preventing us from moving to a newer gcc compiler -- at some point G4 might only run in the newer compiler, so this could become a problem.  The report is that the Gaudi people are working on this, but no one at the meeting knows a target date.  Stay tuned....

bullet24 June 2002 in MOON VRVS
bulletTopics:
bulletBeam test statistics (Eduardo)

Results were based on a pencil beam into a corner tower.  Eduardo will make the cumulative plots, and Steve and Eduardo will review the results to understand and correct any inefficiencies at low energy.  The inefficiencies may be due to edge effects, so the analysis will also be run over the full face of the LAT.   The expected statistics as a function of energy (with bremsstrahlung spectrum) will be simulated.  Report at the next meeting.

 
bulletAround-the-room discussion of work status

Mark is working on low-energy CAL response.  Plots in a few weeks.  

Leon is working on making the GLEAM geometry more flexible, to handle all our configurations (single tower, 2x2, 1x4, EM) -- Toby suggests making these standard configurations, selectable in the joboptions file.  They will figure out how to do this.

Francesco will look into the apparently strange handling of muons by GLEAM reported by Bill.  2 GeV muons appear to be making EM showers (not just soft delta rays).  Bill will post some event pictures and Francesco will investigate.  Report at the next meeting.

Tracy has been working on the MCTruth info in the ROOT output files, and constructing tools to use the info.  This will be very helpful for understanding TKR recon performance.  He also found some flaky behavior in a complex ROOT macro -- an example will be sent to Heather for diagnosis.  In the meantime, he has started running ROOT in Visual Studio to use the debugging tools.  Leon has tried Tracy's implementation of this, and gives it high marks.  A platform-independent solution should be found for this (feedback will be given to Heather).  Report at the next meeting.

Nicola is continuing to work on the GRB simulator, which will be used to evaluate the localization performance.  Results soon, comparing his generator with other models and real burst lightcurves.

Toby attempted to bring pdrApp in line with Gaudi V9 so that pdrApp can use the newer recon, but this proved to be too difficult.  On the GLEAM front, protons can now be simulated.

Bill reports that Brian is rewriting two fit classes to run faster and be more user-friendly.  He also reports the G4 propagator seems not to be working correctly (jumps over volumes), and some needed member functions are not present.  Tracy had a look at this, and sees how to fix it.  Update to come this week.

bullet10 June 2002
bulletDiscussion of hardware trigger throttle (SR).  See slides in ppt and pdf (pdf file is BIG).
bulletNext meeting: 24 June 2002 MOON VRVS.  Topics: Beam Test Statistics (Eduardo), AOB.
 
bullet3 June 2002
bulletFirst organizational meeting.  See slides here.
bulletWe discussed who is working on what.  Here is a brief summary:

Eduardo: check statistics needed for beam tests using the simulation.  Running different configurations (angles and energies) using pdrApp.  Needs a first set of cuts to represent inefficiencies.  Steve will send Eduardo a ROOT macro.  Work is starting now, and should be complete during the summer.

Francesco: verifying underlying physics in G4 as implemented in GLEAM, particularly EM and hadronic showers.  Expect a technical note in ~1 month.  Also interested in triggers for bursts.

Toby: working on how best to parameterize the performance parameters.  Will work with Seth.

Nicola: GRB simulations and Transient Source sensitivities.  Implementing sources in the flux package.  Will help out with studies of on-orbit LAT-SC alignment.

Tracy: TKR performance; and tools for reading ROOT trees and doing analysis.

Richard: system-wide test suite; CAL in coordination with Mark.

Bill: over summer, produce and analyze calibration data sets to measure how well TKR recon is doing against the requirements; how to combine tracks together to form gammas; then, move on to background elimination issues with new tools.

Mark: Energy measurements at low energy (will talk with Bill, who has also been working on this); also interested in background rejection and trigger studies.

Hiro: TKR alignment; beam test statistics studies; performance parameterizations.

Michael and Johann: vertexing and use for gamma direction reconstruction and background rejection.

Steve: background rejection; onboard filtering support for JJ; hardware trigger throttle issue(see 10 June meeting); instrument performance studies.
