| Alcohol | We use either ethanol oriso-propanol for cleaning purposes. | 
| Bath cryostat | Dewar to cool CCDs which containsa few liters of liquid nitrogen and can be operated 20 to 50 hours withoutrefilling. | 
| CFC | ContinuousFlow Cryostat. Cryostat type which doesn't contain a vessel with liquid nitrogen,but it is cooled with a small amount of continuously passing through of liquidnitrogen.  | 
| Fiberglass | Epoxy material filled with fibres. | 
| PCBs | PrintedCircuit Boards. Electronic boards used for internal cryostat wiring and filtering.  | 
| Tank | Vessel inside the dewar which containsliquid nitrogen. | 
| Ultrasonicbath | Metal box for cleaning instrumentsin a solvent with ultrasonic waves and heating. | 
| VITON O-ring | Look for List of Materials | 
| ZIF-Socket | Zero Inforce Socket. Socket used for CCDs in order not to apply forces to CCD pins.  |
