Schematic plan view of a 40-cm disk amplifier module containing a laser disk with the
19-mm-bore flash lamps. The path of the laser beam is also shown. All the flash lamps
on each side of each laser disk are housed within a single pump module. A blast window
in front of the flash lamps protects the laser glass in case of lamp failure.

Power conditioning units are designed as mirror image pairs of each other to facilitate
back-to-back placement in the Capacitor Bays. This design enhances serviceability.
HV-discharge cables to the flash lamps in the amplifiers exit the top of each module
(not shown).

A quad-fold front door allows unrestricted access to repair the power conditioning unit.

The power conditioning control module (PCM) interfaces with the main and PILC trigger
generator modules (TGM), the main and PILC charger control modules (CCM's), the
waveform digitizer module (WDM), and the hardware control module (HCM). LLE's
Ethernet provides communications with the power conditioning executive (PCE) and
the synchronous triggers are provided by the master timing generator (MTG).

Waveform digitizer module (WDM) block diagram. The primary purpose of the WDM is to
digitize and store PFN current waveforms during the shot sequence. Each PFN's current
waveform contains two pulses: a PILC pulse followed immediately by a larger main pulse
as shown in Fig. 4.1. After a shot, the PCM will upload this information from the WDM for
later transmission to the Power Conditioning Executive. Each WDM can handle up to 16
independent channels of on-shot data collection.

The OMEGA EP Power Conditioning Executive (PCE) graphical user interface (GUI)
is similar to the OMEGA PCE GUI. With 66% fewer PCU's in OMEGA EP, the user
interface and status screen could be combined.
