SHOOT Pumping Right to Left
If you've already read the description of SHOOT Pumping Left to Right, this is basically the same, except that Right and Left are switched. Here's the full description:
SHOOT diagram showing configuration to pump helium from right-hand tank to left-hand. On right-hand end, heater is on (to pull helium into tube) and valve is closed (to prevent helium from just flowing back into left tank.) On left-hand end, valve is open (to allow helium easily to flow into tank, without having to go thru porous plug.) Return
