APOLLO Command Module


ACM Front Panel

The APOLLO Command Module (ACM) performs the digital logic functions associated with:

The functions of the ACM have been implemented as a custom CAMAC module based on Altera MAX 7000AE programmable logic devices (PLDs). Specifically, an EPM7256AE chip is used to provide the CAMAC dataway interface and house the module's command set. An EPM7512AE chip is clocked at 50 MHz, and produces the state logic that drives the APDs, the laser, and selects STOP pulses for the TDC.

The PLDs residing in the ACM can be re-programmed in situ, allowing arbitrary modifications to the logic provided the pinouts and external hardware are the same. This means that new modes of operation not yet anticipated can be accommodated in the future.

Many thanks to Tim van Wechel and Allan Myers (and CENPA) for their fantastic job in producing the ACM.
