Functional Description<br />
Vacuum System<br />
Figure 1-15 shows a schematic overview of the vacuum system. The<br />
<strong>Orbitrap</strong> has the following vacuum compartments:<br />
• CLT compartment in the aluminum vacuum chamber (pumped<br />
by the same pump as the linear trap)<br />
• Vacuum chamber (pumped by a water-cooled 60 L/s – for N 2 –<br />
turbopump TMH 071, TMP 1, manufacturer: Pfeiffer)<br />
• Ultra high vacuum chamber (UHV chamber, pumped by a<br />
water-cooled 60 L/s turbopump TMH 071, TMP 2, manufacturer:<br />
Pfeiffer)<br />
• <strong>Orbitrap</strong> chamber (pumped by a 210 L/s – for N 2 – water-cooled<br />
turbopump TMU 262, TMP 3, manufacturer: Pfeiffer)<br />
The forepumps of the linear trap provide the forevacuum for the<br />
turbopumps.<br />
