View source for Construction plan 1/1/2020 - 30/8/2020

The goal is to assemble 450 - 500 modules by the end of summer.

64 CRYTUR crystals available (checked) 250 crystals produced by SICCAS, will be in the 
lab in February

100 PMTs are in the lab, expect to receive 400 more by April.


* Checking crystals

::: Visual inspection  (5 min per crystal)
::: Dimension measurement  (10 min per crystal)
::: Transmission check (20 min per crystal)
::: Light yield (20 min per crystal)

* PMT checking 
::: Diameter check 
::: Check gains (perform check on some randomly selected sample)



=== Module Fabrication ===



* Brazing straps
::: Procedure - brazing setup exists, has to be finalized
::: Time per module - 30 min


* ESR shaping 
:: - ESR cutting   (cutting tool exist)
:: - Shape in the oven (2 tools exist, 30 min per cycle]


* Tedlar cutting
:: - Tool exists
:: - Time per module - 15 min


* Crystal wrapping 
:: - Tool exists
:: - Time per module - 20 min


* Preparation of silicon cookie
::  - Tool in preparation
::  - Mix RTV
::  - Pour to the gluing fixture
::  - wait 1 day to set, move to the oven for several hours
::  - Time:  2-3 days per 30 cookies


* Module fabrication
:: - Time per module: 30 min
