Telescope Chip Status Prototype telescope chip (MimoStar 2) at DESY since April Work on general understanding is ongoing. MimoStar 2 USB Imager Board

How ? MimoStar Test Bench

Ingrid-Maria Gregor, DESY Infrastructure Telescope Mechanics  Box 1:  fixed position, optical bench for three reference planes, temperature controlled  Wall to DUT can be removed  Box 2:  movable in z-direction, optical bench for three reference planes, temperature controlled  Wall to DUT can be removed  Box 3:  Gap between 2 and 3, closed by thermal cover  XY-table: external with “long” mechanical structure to locate the DUT between the reference planes (accuracy: 10um, repeatability: <0.5um per axis)  This “arm” is the interface for the different DUTs  Accuracy of mechanic: 0,1mm (alignment runs foreseen)  boxes can be placed into magnetic field, not the XYtable (cost reasons) z y

Ingrid-Maria Gregor, DESY Infrastructure DAQ Infrastructure  2 PCs to be used for the testbeam have been ordered  One for data taking (Windows XP)  2 parallel ports  6 USB ports  Large disk (~0.5 – 1TB)  One for analysis (Scientific Linux 3)  Working on the optimal solution for data sharing and storing  NAS solution  PCI/VME interface ordered

Telescope Simulation

First Results

PCMAG Interface definitions between DESY and KEK are agreed Some savings due to reuse of HE tranfer line and power supply However, movable support will be more expensive than originally planned

Reuse from KEK

Test beam area 24 Shielding stones moved –to allow access for PCMAG –Improve the shielding Interlock rebuilt Holes for cables from chamber to counting room New lights are being installed General cleanup Whole area was painted

Test beam area 24

Test beam DESY Discussion between U. Kötz and J. Maidment (M): –No changes in near future (→ 7/07) –Electrons, 6 Hz (160ms), /bunch –7/07 → 12/07: positrons –*NO TESTBEAMS* for > 6 months in 08!!! –After that *ONLY POSITRONS* –Maximum energy: 6 GeV
