Prototype Status

The first sample counter from McNeal is due in on March 14.

Mechanical Design

accuracy of placement of sipm's with respect to scint. in transverse and longitudinal dimentions

set screws to set long. gap

werner: critical dimention in radial position

light tight requrement reflective material separating counters

start with precision machined inner rohacell shell add scint add outer shell

look at support structure in hall b

support of target vacuum chamber, possibility of causing leaks

spriing loading, pull the structure back againsts target structure

200 microns on radial dimentions

more sectors allows more adjustiblity need allignemnt criteria

don't forget temperature stabilization talk to fernando about temperature

sasha has samples, maybe we can look at those

Contract Status

statement of work
