This page includes details for the hollow cathode lamp (HCL) power supplies. Four HCLs are used in KPF:
Thorium-Argon ‘Daily’
Thorium-Argon ‘Gold’
Uranium-Neon ‘Daily’
Uranium-Neon ‘Gold’
Note initially we had four Photron P209 power supplies for the HCLs, but one failed in December 2022 and with regard to a repair Photron proved difficult to work with. We then moved to a Green Scientific power supply as a replacement (although unfortunately these are only set up for 220V, hence a voltage adapter is needed).
