IG2 Quick Start Guide
Unpacking the IG2
1. Inspect the boxes for any visible damage. If there is any damage, please report it to the shipping
company immediately.
2. Remove all components and inspect them for damage. If there is any damage, please report it to
the shipping company immediately.
3. Verify that you have the following items. If any are missing, please contact RBD Instruments at
541-330-0723 or e-mail us at [e-mail].

1. Install the 04-165 Ion Source in the vacuum system.
2. Bake the system at 150° C to 200° C for 4 to 8 hours. You may use heat tape to bake only the 04-
165.
3. Install the 32-175 Control in a 19" electronics rack or use on a desktop.

5. Connect the 04-165 Ion Source to the 32-175 Control using the IG2-CA1 cable.
6. Connect the AC power cord (120 VAC OR 230 VAC) to the 32-175 and then plug the AC power cord
into the power outlet. DO NOT TURN ON THE POWER to the 32-.

Method 1 - Measure the Target Current:
Using a picoammeter with a +90 V bias to measure the target current. Adjust the Focus knob on the
32-175 to maximize the target current (typically 5 A). The maximum current corresponds to the
highest current density (smallest beam diameter).
