Re: Hamamatsu APD - Homesteak site chosen

["George Lolos" <George.Lolos@uregina.ca>]

Hi Alex:

The SiPM Hamamatsu just released for sale is the "standard" 1mm x 1 mm
sensor, very similar in all aspects to CPTA and MEPHI SiPM's.  One
difference is the optimized sensitivity to the blue region and it's
developed to address (initially) the requirements of the T2K near
detector. Hamamatsu also pursues 2 mm x 2mm sizes but to the best of my
knowldge they have not pursued larger arrays.

Cheers,

George

Hi All

The two items below came in this morning - PhysicsWeb Summaries.  The
first item is from  Hamamatsu - the second - an interesting news item.
I'm sure many know the Hamamatsu material - but just in case....

Photon Counting with Silicon APD
Hamamatsu Photonics introduce the new multi-pixel photon counter 
(MPPC), the S10362-11 series, for photon counting applications. The 
device features brand new technology utilizing a Geiger-mode 
avalanche photodiode structure for ultra-low-level light detection 
and is supplied in a compact 5 mm package.

   US chooses site for underground lab (Jul 11)
   http://physicsweb.org/article/news/11/7/10
      The US National Science Foundation (NSF) has ended years of
uncertainty
    and finally decided on the former Homestake gold mine in South
Dakota as
    the site of a huge new underground laboratory for physics and other
    sciences. Shielded by up to 2000m of rock, the lab will be an ideal
    location for experiments that require screening from cosmic rays and
    other background radiation, such as those studying neutrinos or
proton
    decay. The NSF chose Homestake from a shortlist of four candidate
sites.
