Mechanical
The High Voltage module (HVPS) of the TT-3/6/8 must be placed in a level
19 inch rack or other suitable cabinet that is capable of supporting a minimum of the following
weights.
TT-3: 100 lbs (45 kg)
TT-6: 200 lbs (90 kg)
TT-8: 300 lbs (135 kg)
The HVPS must be secured in the cabinet before electrical connections are made.
System Grounding Practice
A good ground is necessary to assure safe and proper operation of the power supply (see
page 15, #1. and section 7, Figures 8-A through 8-E).
Grounding
Proper grounding is the single most important aspect of the installation of the E-beam. During
arcing events, RF noise is generated that must be properly driven to ground to avoid
interference/damage. For this reason, the E-beam ground must be separate from the
electronics rack ground and ideally as short as possible. Improper grounding can lead to poor
performance, interference with other equipment, damage to E-beam electronics or other
equipment, or even shock potential.
Do not depend on water pipes for the system ground connection. Because of multiple joints
and sealing compounds, water pipes typically do not make an earth ground. Keep in mind this
is a high frequency as well as a DC ground.
Regardless of the method of grounding, the first point of connection for the ground
cable/strap is always the E-beam chamber. There should be a specially designed ground bar
welded to the chamber for this purpose. The strap, if used, should be "sandwiched" between
two bars to ensure a broad area connection.
