The tank must be closed and the machine operating before I go overseas. Its still possible. I have booked on the over night train Aachen / Cologne/ Vienna arriving Thursday, 16 October at 09:40. I'll be leaving on Sunday, 19 October at 07:00 by air Frankfurt then on to Newark. The abstract I propose for my talk follows. Looking forward to seeing you soon, Regards, David ***************************************************************** "All in the Accelerator Family" David Weisser Nuclear Physics Department Australian National University Canberra ACT 0200 AUSTRALIA Abstract The 16 MV accelerator at ANU and the 3 MV at VERA share the good and bad traits of all NEC machines and, of course, obey the laws of physics and the law of Murphy. However carefully accelerator tubes are assembled, there often are subtle and sometimes blatant off axis biases. The main accelerator tubes in the 14UD suffer from the subtle kind and the one set of pre-acceleration tubes, from the blatant ones. Two strategies for accommodating these non-cylindrical accidents are described. A new gas stripper has just been installed. Although it is premature to brag about its performance, a novel installation of the fibre optics, which communicate to the terminal, looks very promising. ****************************************************************** David Weisser e-mail: david.weisser@anu.edu.au Nuclear Physics Department Fax: + 61 6 249 0748 Research School of Physical Science & Engineering Phone: + 61 6 249 2080 Australian National University Canberra ACT 200, Australia ******************************************************************
