    "abstract": "The peak current limit for the Fermilab Linac was recently studied. The\npurpose was to learn what components of the present Linac can be used for the\nfirst stage of a proposed proton driver[1]. For this application the Linac must\nprovide a H- beam in excess of 5000 mA-msec per pulse. The original Fermilab\nLinac was designed for protons with a peak current of 75 mA and a pulse length\nof four Booster turns (~10 msec). The high energy replacement was designed for\na peak current of 35 mA and a beam pulse length of 50 msec. The present H-\nsource cannot deliver more than ~80 mA which produces 55 mA in the Linac. Using\na proton source allows the system to be tested to currents of ~100 mA and pulse\nlengths long enough to observe the effects of long pulses. This test has shown\nthat the present Linac can accelerate beam having a peak current up to ~85 mA\nwith beam loss comparable to the present Linac operation (~45 mA). The results\nof the test will be presented.",
