<p>Comments: 60Co source with AIDA in, red box, CD 395 . The source is not centered. It is positioned (the center of the source) at 14.6 cm</p>
<p>from the beam side external edge of the frame (lower NaI numbers). The holder is touching the nose of AIDA.</p>
<p>The nose of AIDA is 16 cm from the external edge of the frame (down stream). In that position Si # 3 is at the center of the DTAS according to Tom.</p>
<p>We have to be very careful when AIDA is moved in. Some of the AIDA flat connector cables are touching the connectors of our NaI cables.</p>
