Plans and future challenges
1 year goal (until the start of data taking mid 2007):• active tuning of the experiment software + documentation• active involvement in optimizing the alignment strategies• active involvement in designing the analysis strategies• collaboration with the HIP tracker project (test beam)
long term (data taking and running the experiment):
need all (and even more) manpower to:• maintain + improve software with real data• gradually improve the software alignment• control the quality of data• do competitive physics analysis• strong response to the computing challengeIn short: computing, calibrations, physics analysis
