Uh Oh....here they come

This is a electronic diagram dwg completed on my Mac SE30 years ago .. 1987. Talk about screen redraw. A cup of coffee and a walk about the bldg would do it.

Fascinating story -

The commercial power supplies (10 each) were custom-built into safety-interlocked large metal enclosures (4 doors) trigger-timed 300amps at 3000 volts pulsed current (sine wave). The stored energy in this supply could kill a human. The recharge tube cost $800 each and was socketed into a $1000 silver-plated triaxial air-cooled mount. The tube itself was ceramic with a metal water-cooled jacket. Sourced from EGG Industries, one tube per supply.

The supplies were paired two to a single magnet. Locomotive-sized cables carried the current. The scheme was to deflect Linear Accelerator (2 miles) generated electron or positron (anti-matter) bunches north or south. 12 channels of exclusive-logic trigger timing dumped the stored current into the magnet just when the electrons were passing through. The magnet's timing system was synchronized with the Linac's timing system.

My job at the time was to maintain both the trigger system and the supplies.

Today I use the Mac as a tool to generate Job Orders, Computer Database, Drawings, Cost Estimates as part of the Controls Dept. Vacuum Electronics Systems.

Largest cost estimate: $52 million for the Next Linear Collider Project Vacuum Electronics. Not the same dollars, but the 1930 Empire State Bldg and the Golden Gate Bridge were built at an approximate cost of $34 million each. The NLC Project totaled $7.5 billion. Congress hasn't approved the funding, but we here at SLAC are still working on some phases of it.
