Hello,

Jie has completed 4 boards of the QWAD adapter, for one plane (see 
attached).
I am leaving for JLab on Thursday and will the taking them along. The 
remaining
ones will be shipped when they are ready.

Cheers,

Michael

Hi Michael,

I'd let you know that four adaptor boards are ready to be brought to 
JLab. Attached please find the instruction about the connections between 
a silicon strip detector and four adaptor boards. As the ordered 
digi-key components just arrived, I didn’t get a chance to make the 
resistive jumpers for QWAD yet. However, I have eight resistive jumpers 
(for 16 channels) built with regular resistors, instead of SMT 
resistors, available right now, which could be used for JLab tests. I 
don’t know when you will go to JLab, I’d try to make more resistive 
jumpers if time permit.

I couldn’t find you today, so I’ll leave those boards and resistive 
jumpers on my desk in Rm#510. Please feel free to pick them up at your 
convenient time.

Cheers,
Jie
