Lithium Stripper

Info

The Liquid Lithium Charge Selector(LLCS), or simply lithium stripper, is used to strip certain charge states from the beam before it is accelerated even further for better transmission. What's unique about this peculiar device is that rather than using a metal foil of gas to strip the beam, a film of liquid lithium is used. The liquid form is advantageous over the other options because this option allows for higher charge states. With lithium, its low melting point, low vapor pressure, and high heat capacity makes it the best to use.

One main drawback about liquid lithium though is that it is extremely reactive with oxygen and nitrogen. To migigate this hazard, a containment vessel surrounds the lithium film device. This vessel is always filled with argon, this way if a leak is to ever occur, the argon can immediately displace the gasses inside and prevent any catastrophic reaction.
