Hi Ed,

Yes, it indeed looks like a million dollars item, don’t forget the additional $1.4M paid for the staves 😉

 

Cheers,

Ming

    Hi Ming,
     That is great. It looks like a million dollars., or at least
    $4.8M/6=$800k. Congratulations to the whole MVTX team.

Dear all,

I am very pleased to share the following photo of the first MVTX outer layer-2 half-detector that was successfully assembled at LBNL today, congratulate the whole MVTX team to reach this milestone!

Based on CMM measurements, one in principle could know each sensor chip positions better than 20um from the perfect model in this assembly! (Let’s confirm it with real data)

    

Cheers,

Ming
