| - Turn up the **ionizer** heater. The ionizer operates at 21-22 amps. Keep in mind that the current will fall slightly as the ionizer gets warmer. Keep adjusting the current until the ionizer is stable at 21-22 A. It should take about 1 minute to reach 21 A from the standby value of 10 A. | - Turn up the **ionizer** heater.

| - | - Set the cesium **reservoir** heater to 0.290. This should be enough to give ones of microamps beam for p and d. A setting of about 0.310 - 0.320 should produce tens of microamps. The reservoir current should not exceed 0.320. | + | - Set the cesium **reservoir** heater to 0.260. This should be enough to give ones of microamps beam for p and d. A setting of about 0.270 - 0.275 should produce tens of microamps. The reservoir current should not exceed 0.280. |
| - Set the Glassman **extractor** power supply to 12.5 KV. Check to be sure the current is less than about 5 milliamps and the "control milliamperes" light is NOT lit. High current indicates that the source needs to be serviced. | - Set the Glassman **extractor** power supply to 12.5 KV.

| - Set the Glassman **target** power supply to 6.5 kV. Check to be sure the current is less than about 5 milliamps and the "control milliamperes" light is NOT lit. High current indicates that the source needs to be serviced. A newly installed pellet may cause instability for the first hour or so, but will become stable. | - Set the Glassman **target** power supply to 6.5 kV.
