Hi all,

Each set of hybrids (inner + outer) is 13 g, so the total weight of hybrids is 13*12*3 g = 468 g. 

Regarding the integrity test for the soft tube, my colleague from the mechanical engineering department will try to do the pull test first and we will keep you updated. 

Cheers,
Yi

Below is the homework from the meeting:

1. What is the total weight of the kapton in the detector?
-> Yi will measure the weight of the hybrids

2. Will the cooling soft tube maintain its integrity (compatibility with NOVEC, no breaking under pressure) after radiation and temperature variation?
-> Yi will discuss with AIDC/Rahul. One possibility is to measure the burst pressure after irradiation (need to find a facility/setup that can measure the burst pressure). Another possibility is to connect a tube after irradiation to the cooling system under test at BNL (Yi will check with Rahul).

Zhenyu
