Minutes of the UVic Testbeam meeting held Friday, January 9 2004
(present: TI, TH, ML, RK, MF, AA)

Michel pointed out that it is time to get the abstracts ready for the WRNPP conference, and to arrange travel for those who are going. Tayfun's abstract is ready. He read it out to the group and everybody thought it was good.

Tayfun reported that he reproduced all the EMEC Ntuples with Naoko's new code (ie, new weights).
With the new Ntuples, he ran his position resolution study on his `good run list' and found that requirements for this run-list needs to be improved, in particular the timing selection. He showed plots of the position resolution obtained with the second EMEC layer as a function of beam energy. It was obvious from the plot, that the selection needs more work, but the machinery is in place now to modify the selection and rerun the analysis quickly. A close eye should be kept on the individual fits - some points looked like they were too good to be true, which could be due to a fit gone awry.

Tamara used the new EMEC Ntuples and looked at the response vs timing phase for the runs she is analyzing. She finds that there isn't really any significant change in the behaviour, but hasn't had the chance to figure out yet, why she doesn't see an improvement whereas Tayfun and Naoko do. Michel pointed out that nobody has looked at the effects of the new weights in hadron runs yet. Maybe it could have to do with the fact that electron showers have small clusters with lots of energy in each cells whereas hadron showers have large clusters with only a little bit of energy in each cell.

Margret continues to study the G4 code. She has simulated an x-scan of 150 GeV electrons (from xcryo= -26cm to +26cm) for Tamara to look at.
She also has the feeling that the `left' and `right' leakage counters are reversed. This appears to be confirmed by some simple plots obtained from the x-scan runs. An email has been sent to Pavol w.r.t. this.
As a cute aside, Margret also showed a picture of the testbeam setup as obtained with the G4 visualization tool.

Richard mentioned that Asok would be willing to install our G4 code on mercury, where jobs would run significantly faster. Everybody agreed that that would be a good idea. Margret will instruct Asok as to what is needed for the setup.
