Hi Sebastian,

the start detector(tof start) consists of two planes of scintillator fibers(~ 2000 fibers).
they are surrounding the region of the secondary target(
radius of ca 8 cm).

The time resolution requirement for a good mass separation(pion from kaons) is about 500ps in combination with the tof barrel(scintillator)detector with a time rsol of 80 ps.

i send you the polot for the detector acceptance
for the Xi minis in the secondary target(small si tracker)
for us is specially important those with a total momentum lower than 0.5 GeV/c( those with a higher propability to be stopped and to form the hypernuclei)

plots are attached to this purpose.
best regrads
alicia.
