Benchmark <strong>of</strong> elastic collisions model<br />

Be injection w/o <strong>plasma</strong> . . .<br />

A weight gain <strong>of</strong><br />

1.5*10 -4 g was<br />

registered in<br />

experiment<br />

Be oven<br />

Estim<strong>at</strong>ed<br />

injection r<strong>at</strong>e<br />

4.03*10 18 Be/s<br />

Target<br />

2g <strong>of</strong> Be is spent in 10 hours <strong>of</strong> oven oper<strong>at</strong>ion.<br />

This gives a r<strong>at</strong>e <strong>of</strong> about - 3.7*10 18 Be/s.<br />

W/o elastic collision with neutrals there would be no Be <strong>at</strong> target!<br />
