. Flux about 1-3E13 p/hour/cm250cm long table + thermally insulated box, scanned horizontally through 10cm.Space for maximum of three 10x10 cm2 sensors + some passive materials.
PS-T7 area, irradiation facility maintained by M. Glaser
Passives, e.g.
glue, grease.
RPC beam monitor + Activation Foils (at Entry and Exit)

Birmingham Cyclotron
26 MeV proton beam
1cm
2 beam spot Ni foil dosimetry, pin diode dosimetry High dose irradiation (1016 neq cm-2) takes 2 days Cold box similar to CERN Can also irradiate without the cold box (bigger objects)
Services
Faraday Cup (Charge)
Initial installation, alignment and testing
in old beam lineSlide5
Birmingham Status
Beam line has moved
First irradiation was last week (4 mini 1 by 1 cm Si sensors)
Irradiated to 2.5e15 p/cm2 (in 22 minutes) Will be faster when we install the sheilding wall (ran at 0.25μA, could go to 1μA) Didn’t use the cold box There is no schedule for Birmingham (just request)Slide6
Summary
CERN PS shuts down the end of this year (2 months of beam left)
Birmingham Cyclotron is coming on line
