The C337 is a single width CAMAC module used to "OR" the permit outputs of four C336 SVX Radiation Dose Integrator modules and four C335 SVX Radiation Dose Monitor modules for SVX protection at D0. The module also interfaces with a rack mounted panel for alarm sounds and control pushbuttons.
When a permit from a 335 module drops, the 337 will drop the permit out to the D0 service building, causing the circulating beam to abort. The module will also light a LED and sound an alarm on the rack panel. A pushbutton is provided on the panel to silence the alarm. Another pushbutton on the panel is used to acknowledge the abort and reset the permit out (after the 335 is reset).
When a permit from a 336 drops, the 337 will light a LED and sound an alarm on the rack panel. A pushbutton on the rack panel will silence the alarm.
