• Simulation of cooling process
• Development and test of prototype power
  amplifiers
• Design, construction, and test of pick-up and
  kicker prototypes
• Test of complete prototype system

Tentative Schedule for 2007

• design and test of notch filter in ESR ? autumn
  2007
• design, manufacturing, and test of electrode
  modules, plunging units and other tank
  subcomponents ? summer 2007
• design, manufacturing, and test of complete tank
  ? beginning 2008

Status

• Pick-ups and Kickers for stochastic cooling are
  an indispensable part of the FAIR project
• COOLSB1 is delayed, but rearrangement of
  resources (manpower) is planned to get pick-up
  and kicker prototypes in early 2008
