ELECTRONIZED C H E M I C A L S C O R P O R A T I O N MIDWEST IRRADIATION C E N T E R
SELLS
High Voltage Engineering Corporation, Burlington, Massachusetts 01803, USA Electronized Chemicals Corporation (a subsidiary of High Voltage Engineering Corporation, foremost developer and manufacturer of nuclear particle accelerators for science, medicine and industry) has sold its Midwest Irradiation Center. The Center w:ts purchased by a private group headed by Mr. Alan Peterson, former manager of the facility and now president of Midwest Irradiation Center, Ivc., a newly-formed company which will operate the facility. The Midwest Irradiation Center has been operated by Eleetronize I Chemicals since 1962 on space leased at Rockford, Illinois. The facility houses a 12-MeV (million electron volt) linear accelerator which has been useu primarily for contract rental irradiation services.
PROGRESS AT GUNDREMMINGEN NUCLEAR POWEb. STATION
Allgemeine Eleh~ri~itiits-Gesellschafl (AEG), Nuclear Energy Division, AEG-Hochhaus, 6 Frankfurt (Matn)-SlO, Germany After the delivery and installation of the forced re~ circulation pumps for the reactor and after the completion of the external concrete lining of the reactor steel containment, both the assembly and construction g~)rks a~the site of the Gundremmingen Nuclear Power Station are mostly finished. The work now concentrates entirely on putting the last touch on the equipment and on the preoperational tests of the individual plant components and systemS. At the end of October 1965, trial operation of the turbo-set with non-radioactive steam coming from'the two permanent boilers of the heating plant and four temporarily installed auxiliary boilers was started. The turbo-set showed a good running stability so that a final balancing of the low pressure rotor, which was fitted out with blades at
the site, became superfluous. At the end of February 1966 the first fuel elements are expected on the construction site.
EQUIPMENT FOR PARTICLE ACCELERATORS
Allgemeine Elektri~itiits-Gesellschaft (A EG), Nuclear Energy Division, AEG-Hochhaus, 6 Frankfurt (Matn)-$10, Germany The Bonn 3-Gee-electron synchrotron, presently under constx~ction, will recieve a capacitor battery from AEG in which the demagnetizing energy of the magnetic blocks, arranged in an annulus, is stored. The MUnchen-Garching Institute for Plasma Physics received a condenser bank of another type. One of the world's largest batteries, the ISAR I pulse battery, was built by the Institute in cooperation with the firms SSW and AEG under AEG sponsorship and became operational early 1965. It has a pulse energy of 1.5 to 2.7 MWs. in the preliminary experiments aiming toward nuclear fusion such a pulse battery serves to heat up plasmas to extremely high temperatures. The plasma, a gas of ionized deuterium, is exposed for a few millionths of a second to a magnetic field of approximately 200000 Gauss and heated up by the concomitant compression effect. Recently this Munich condenser bank made it possible to attain 60 million oc, the highest temperature ever reached in any similar experiment carried out until now. Highest precision is required not only for the magnets but also for the supply of their exciter power. Therefore AEG is manufacturing extreme constancy rectifiers with a relative current constancy of less than 10-4 for the power supply of beam directing magnets and quadrupole lenses. These power supply units can work to~ether with the A E G nuclear resonance magnetic field meter in such a manner that magnetic fields can be controlled with the precision of the nuclear resonances of protons. Such A E G power supply units are in use e.g. at the Karlsruhe cyclotron and for test magnets at Mainz and Heidelberg.
