Hi Will,
I give you an update about our CalCom activities. As you probably
remember, we achieved two steps in using CLAS software.
- Our single pion event generator has been adapted to BOS format and
its output is accepted by GSIM. By the way with that generator
and the old-fashioned FASTMC we performed to two studies about
pi0 calibration in EC and EC1 and neutron calibration for EC1
that are reported in two CLAS notes: those notes are available
on our CLAS Web page (http://aiacehp.ge.infn.it/bibl.html) and
I think also on the CEBAF Web page.
- Then we tried to study the pi0 response of EC1 processing the
generated events with GSIM, then accessing the GSIM output
directly and creating HBOOK ntuples with the digitized data
for ADC and TDC (no RECSIS for the moment). Due to some problems
in TDC response we decided to switch to a more simple muon simulation,
generating muons from the pointlike target. These checks are still under
way and we are also trying to compare the simulated muon response
with our cosmic rays data from the real measurements on the
EC1 module. We are again in touch with Harut, so I believe
we will understand this GSIM output quite soon. Next step will be
then to go to pi0 and see the total energy response.
I am planning to put some pictures of the generated pion events
and of the GSIM response to muons on our Web page as soon as
I have some time. I'd like also to drop some simulation
in the CLAS repository. By the way I think that if a version of BOS
libraries for Digital Unix exists, our single-pion-BOS generator
could also run on Alphas and this could be quite a breakthrough
in speed: I used a fitting program for the two pion events
on HP735 and on Alpha 250-4/266 and the latter one was about
5-6 times faster !!
As final remark, I won't be at the collaboration meeting
tomorrow, but I plan to be a couple of days at TJNAF in the
last week of October.
Best Regards
Marco
