[1-1] Development Since the Last Discussion
About a month ago, we decided to open to the public various
software resources used in the past JLC simulation studies.
Preparation for this is on going and some writeups have
already been added to our offline analysis page
The home page still needs a major overhaul, though.
It was also pointed out that shifts to an object-oriented
framework in parallel would be necessary in near future.
[1-2] North American Activities
We can see a similar trend in the draft written by M.Peskin
for the north American linear collider detector simulation
study available from
Some extracts from Peskin's draft read:
1) Our goal is not to bring a specific detector design to
Barcelona international meeting, but rather to bring a
great deal of data that will make the discussion of
design options concrete.
2) a simulation package using GISMO, a C++ class library ..
Physics analyses can be done in C++ using the CERN
analysis class library ROOT...
3) We plan to introduce to this simulation package and set
of questions to the linear collider detector collaboration
at the Keystone meeting at the end of September.
November to discuss analysis methods, exchange tools, and
iron out any difficulties in getting started, in early
February to review the first results, and at the end of
March to criticize the almost-finished analyses.
As for the simulation studies for detector R&D, we agreed that
we had better stick to the current R&D programs that found their
roots in the Green Book. For these studies the most effective
way to prepare for the Barcelona meeting is to polish up "JIM".
This does not mean, however, that we can delay the shifts to
an object-oriented analysis framework.
In our case, systematic development of the object-oriented
analysis framework is expected to commence as soon as the first
ACFA Joint Linear Collider working group meeting is held.
It is, however, highly desirable to start investigating possible
future directions as soon as possible. As the first such an attempt
J.Kanzaki will review the GEANT4 project in a Friday meeting
(the date will be announced later).
A.Miyamoto, who is now porting "ROOT" to the ccjlc cluster (HI-UX),
demonstrated the "ROOT" interactive session after the meeting.
