The baseline solution for providing high voltage to the PMT array is the commercial LeCroy 1440 high voltage system. This will clearly work, but is costly. Largely because the 1440 system provides significantly more computer control capability than is actually required given that voltage changes are likely to be infrequent. The most important requirement on the high voltage is the ability to reduce the gain on tubes when the light level is high. The committee notes that there are other less expensive solutions available. An example would be a voltage divider equipped with a trim pot to adjust the voltage of an intermediate dynode. This is an old-fashioned way of balancing gains which preserves uniform timing from tube to tube and requires only the distribution of a single common high voltage to the array. Such a base can be equipped with a relay or other electronic switch to change to a lower gain when necessary. Clearly either approach will work. A custom system might be cheaper and potentially more robust, but would of course require development effort. The committee recommends that the collaboration look at the cost versus benefit for the two approaches before finalizing a decision to buy a commercial system.
