- Switch to the new reference foil or compound. Reference foils are in the small wooden box of foils at the beam line.
- Low-energy configuration (E < 5 keV, using low-Z box with bellows or cryostream bag)
- Move CALVERT to out position (CALVERT = 4).
- Open feedthrough for motorized vertical CALVERT holder by loosening and removing C-clamp.
- Pull feedthrough out completely.
- Remove sample holder plate for old reference foil or compound and press new reference onto double stick tape on mount. Align holes on plate to holes on mount.
- Re-insert CALVERT holder and replace and tighten C-clamp.
- Attach I2 cable to BNC connector below motorized vertical CALVERT holder.
- High energy configuration (E > 4.9 keV, not using low-Z box with bellows or cryostream bag)
- For samples which will transmit beam through them, place foil in holder in front of I2 ion chamber. Attach I2 signal cable to I2 ion chamber.
- For thick or non-transmitting samples, insert foil in the scatter holder before on top of I0 ion chamber. Attach I2 signal cable to photodiode cable on scatter holder.
- Low-energy configuration (E < 5 keV, using low-Z box with bellows or cryostream bag)
- Make sure there are no samples or holders blocking the beam path through to I2.
