1 Profiler Mechanics UpdateINSIDE Pisa Meeting 9/10 June 2015 V.Patera

2 General status Tracker mechanics almost finished ( frame & fibers)Waiting for electronics PCB (beginning July) to finalize cooling system design Calorimeter mechanics started Dose Profiler complete tracking system with the calorimeter support plus 2 spare tracking planes

3 Mechanics: tracker statusAll the tracker plane (6+2 spares) ready: final frames and machined fibers in place Waiting for electronics PCB (beginning July) to finalize cooling system design

4 fiber planes have been machined to match the profile of SiPMs and passive components soldered on the BASIC-board

5 Tracker mech. and coolingasimmetric (0,5 mm) spacers among planes have been drilled; they will help heat transport Final configuration with PCB must be tested for heat flow

6 Calorimeter Mechanics StatusExternal frame, to be fixed to the tracker, finalized Developed a fixing system of the crystals+MAPMT elements Integration with electronics ( and cooling) on going

7 Holding LSF matrices connectors on H8500 will create a space in which an insulated 4 mm x 6 mm Al bar, a spring and a screw will press the MAPMT against the crystal matrix 2 Al bars will press the crystals sideways stiff 10 mm Al structure 1/16: crystal + H8500

8 0,25 mm phosphor bronze foil inserted matrix and MAPMT elements will be pressed against it

9 Stiffness of the systemComplete setup of the 16 Matrices: 20 cm x 20 cm2 LFS calorimeter Test of stability: put the calorimeter orizontally -> all the weight leans on the foil and monitor the bending of the foil

10 Stability test After a week, gravity did not succeed to move the crystals phosphor bronze foil could be thinned (250 mm  150 mm)

11 Calo electronic updateLNF electronic service is taking care of calorimeter electronics Preliminary layout ready -> building phase HV PCB modules for H8500 ordered (->Centro Fermi) front-end for calorimeter order is being prepared (12k€+IVA->INSIDE) Concentrator FPGA board design ok-> order will follow

12 spares

13 6 X-Y fiber planes + 2 spares readycalorimeter structure almost ready waiting for electronics to finalize cooling system 210x210x0,3 mm3 foil to be inserted here crystal fixation system thanks to MARCO MAGI
