Minutes of the DESPEC Ge array working group meeting 
at GSI, February 11th 2005

Participants: A. Algora, D. Balabanski, W. Gelletly, J. Gerl, P. Greenless,
A. Jokinen, A. Jungclaus, I. Kojouharov, M. Leino, Z. Podolyak, D. Protic,
B. Rubio, K. Spohr

1) short discussion about planar Ge in general (GREAT planar Ge works
    ok now) - more information in the next meeting
   
2) discussion with D. Protic from FZ Juelich about "his" planar Ge

   R&D work to be done:
   - reduction of the size of the guard ring if possible
   - at least use the guard ring to suppress "bad" events (for that
     any signal is ok)
   - in case of many channels cabling is a problem (thin Kapton cables
     lead to bad resolution)
   - Is it possible to place the first stage of the preamp close to the
     detector ?

3) We decided to consider both planar Ge as well as Clover type detectors
   in the simulations for the Ge array.
   
   The groups from Bucarest, Debrecen, Madrid, Paisley, Sofia, Surrey and
   Valencia volunteered to work on the Monte Carlo simulations. So far I
   got the names of the following persons:
   
   Mihai Constantin	Bucarest
   Alejandro Algora	Debrecen	        planar
   Andrea Jungclaus	Madrid		planar
   Pavel Detistov	        Sofia	       	        Clover
   Luis Caballero	        Valencia 	        Clover
   
   The groups of Paisley and Surrey should give me names as soon as
   possible. I will contact all the people involved in the simulations soon to
   coordinate the work and get started as soon as possible.
   
4) The following persons volunteered to think a bit more in detail about
   the experiments we plan to realize with this Ge array and consequently
   about which situations should be included in the simulations.
   
          beta-decay:	W. Gelletly, B. Rubio, A. Algora
	  isomers:	        Z. Podolyak, J. Gerl, G. Rainovski   
	  
5) The next meeting of the Ge array working group will take place the 7th of
   April in Surrey. The simulation group (see 3) should try to get started by
   then (setup the geometry and so on) and the "thinking" group (see 4) should
   be able to provide detailed input for the simulations on April 7th.
