A vacuum chamber has multiple wafer positions, and the wafers are positioned by a rotating pallet. The radiotherapy system includes a gantry on which a therapy beam source that determines a beam axis and two imaging units secured rotatably about an isocentric axis. For example, vibration attenuation modules may be inserted at locations where vibration energy is expected to be maximal. In other embodiments, the removable cartridge includes a crystal source portion, a crystal waste portion, and a re-sealable portion adapted to prevent crystals from leaving the removable cartridge when a transfer apparatus is not present. The method further comprises commencing the data call through the roaming partner by sending the authentication bypass key to the service provider from the telematics device via the roaming partner. The filter cartridge is in fluid communication with the flow meter.
