Current status

Electron gun test repstrap vacuum chamber including pumps and gauges under electircal maintenance. Current tech team; 3 software developers, Ultra high vacuum metal deposition specialist, High voltage system designer. We are particularly looking out for experienced electron gun designers (Electron beam welding/accelerator).

Looking for someone in Harrah's Reno, NV, USA who might have time to attend the conference on our behalf. '"Registration ebeam 2010»ebeam - International Conference on High-Power Electron Beam Technology« is the foremost forum for electron beam technology.Following the success of ebeam2008, Mr. Robert Bakish, VON ARDENNE and ALD will maintain this conference as an important event for the EB community. The conference will once again take place at its historic location at Harrah's Reno, NV, USA from October 24 to 26, 2010 to review the progress and achievements in high-power electron beam technology."'
