    keyword=Spare target heater replaced

    Replaced the broken spare target oven heater. Verified resistance to be around
    20 Ohms when cold, which is what it should be for a good heater. A broken
    element typically has 40 Ohms or infinite resistance.

    NOTE: There are four more spare heaters in a cardboard box in the cabinet next
    to the laser hut. It takes nothing but common sense to replace them.
