In the frame of a collaboration between IHEP (Protvino, Russia) and GSI (Darmstadt, Germany) IHEP developed, produced and tested a superconducting model dipole. The main parameters of the dipole are a two-layer coil,

This electron cooler prototype will not demonstrate the actual cooling but it will allow determining if the electron beam properties are suitable for antiproton beam cooling. An electron beam is accelerated by a 5-MV Pelletron (Van de Graaff type) accelerator and transported to a prototype cooling section. The cooling will take place in a 20-m long solenoid flanked on both sides by a delivery and return beam-line -a total of 60 meters of transport channel.

Conceptual design studies show that with an electron beam current of 200 mA and with a cooling section of 20 m electron cooling in the Fermilab Recycler ring can provide antiproton stacking rates suitable for the Tevatron upgrades beyond Run II luminosity goals. A prototype of such an electron cooling system is now being built at Fermilab as part of the continuing R&D program. This paper describes the electron cooling system design as well as the status of the Fermilab electron cooling R&D program.

Namely, the solenoidal field of 50-150 G should have an integral of the transverse component below 1 G⋅cm over the whole 20-m cooling section . The transverse field components are measured by a dedicated compassbased sensor , which has been designed and manufactured at Budker INP, Novosibirsk. The paper describes results of the field measurements performed on the cooling section solenoid prototypes as well as the design and the calibration procedure of the sensor.
