{\large {\bf Silicon Detector Developments}}\\
Developments since the last meeting are summarised below %\\[1mm]
\end{center}
 
 
\begin{itemize}
\item	{\bf Q-Par Angus}\\ 
First prototype detector (1 k$\Omega \ \Box ^{-1}$) delivered and 
ready for tests.   The second 
prototype (2 k$\Omega \ \Box ^{-1}$) due in two weeks time.
\item	{\bf Micron}\\
Double sided strip detector (NASA flight test module) 
awaiting tests.   Colin Wilburn has 
been in touch to offer more details on this (sending a copy of 
a report presented at a 
conference at Santa Fe). 
\item	{\bf Canberra}\\ 
Quotation received from Canberra on their PAD detectors 
(our PSSSD).   Specification 
looks similar to Micron but cost is higher.
 
Michel Ceuppens, one of their sales and marketing people 
from Belgium, called in for a 
discussion a few weeks ago as he was in the country.   He 
took back a number of technical 
enquiries for Paul Berger.   Paul Berger will be here for a 
meeting on 10 June to discuss 
these points.   It seems they are very interested in working 
towards either design (the sheet 
resistance readout or double sided design with inline 
resistors).
 
Had a chat with Siegfried Hoffman at GSI who uses some 
of their detectors.   Not really a 
similar use, but he had a lot of praise for their devices in 
general.
\item	{\bf Hamamatsu}\\
Prototype detector to the RIKEN design just arrived and 
ready for tests. 
\item	{\bf Intertechnique}\\
Still awaiting a device similar to those they built for the 
MULTICS collaboration which 
they are loaning us for tests.

Had a meeting with Nick Corps from Oxford Instruments, 
Intertechniques representatives 
here in the UK.   He has gone off to get more information on 
their capabilities with regard 
to strip detectors. \hfill $\Box $
