>> Hi Albert,
>>
>> I just wanted to provide an update of the ECAL inventory of supermodules
>> and parts. During the verification of the inventory, we found 1 more
>> supermodule, which has been added to the inventory. You also provided an
>> additional 30 cut springs and 28 uncut springs which will make 56
>> springs
>> (86 total springs delivered on 2/10).
>>
>> These parts have been added to the inventory. We will resume supermodule
>> assembly with the 86 springs you delivered today.
>>
>> The final count from today is 154 of 192 completed supermodules. 38
>> supermodules are needed to complete the project. The breakdown is 14
>> short
>> modules and 24 long modules.
>>
>> To complete the project we will still need 8 wrapped lead-glass
>> assemblies, which you said you and Bihn are working on.
>>
>> We will need 9 long frames. Per our discussion, I will look at the frame
>> parts and verify how many long frames can be assembled from the parts.
>> With the parts on hand, that number will be no more than 4. Again, these
>> are not part of the count until I can verify that they can be assembled
>> into frames. I will have that information for you by Monday.

>> Hi Albert,
>>
>> I completed the inventory of all the supermodules on 02/08/2022. I have
>> also counted the lead-glass assemblies and the frames. These numbers
>> will
>> let you know what will be needed to complete 192 supermodules.
>>
>> I counted a total 153 supermodules on all the shelves in EEL 126 and in
>> the test stand in the Test Lab. This includes the 20 DSG has assembled
>> this year. There is a balance of 39 supermodules to reach 192. The types
>> of modules are not even, there are 81 short module and 72 long modules.
>> In
>> addition there are only 334 lead-glass assemblies which are already
>> wrapped with film and copper in EEL 122 and 126. Lastly, I counted all
>> the
>> pre-assembled frames. There are only 32 total frames. We have enough
>> short
>> frames, but more of the longer frames are needed. I have written in
>> comments on the parts which have shortages which need to be addressed in
>> order to complete the project. The "Need" column does not account for
>> any
>> spares of any parts or supermodules.
>>
>> I will be at the lab tomorrow to look at the leftover frame parts we
>> found
>> in EEL 122, at best these parts might make 3 long frames. I will not add
>> them to the count until they are pre-assembled and checked.
