Main activities and results of NUSTAR 3 in 2005

• Design, production and testing of a low
  pressure gas system
• Design and production of a prototyp of a
  proportional beam
• chamber BC with delay line
• Design and production of new electronics for
  the BC chambers

• In time with Implementation plan of Task 8 -
  NUSTAR 3

3
Low pressure gas system

• Gas system was built and tested (at the FRS)
• Tests showed high precision and reliability

4
New generation of a Time Proportional Chamber
(TPC) for ion tracking

• TPC with new designed C-pad read out was designed
• New TPC is providing two point on the track in
  each dimension
• High precision integrated delay lines were used

BC for Beam Pofile Measurement

• Multiwire Proportional (Ionization) Chamber
• Low pressure 0 1 bar
• Low amount of material
• in the beam area
• Delay line read-out

6
New integrated electronics for TPC and BC chambers

• New integrated electronics was designed and
  produced
• New electronics for readout of 128 channels of BC
  chambers was obtained
