Supplies available at the experiments

The following infrastructure is available at each individual beamline:

1. Power supply

3 circuits, each with RCD, 3x Schuko connectors per circuit, 1x IEC 16A connector, and 1x IEC 32A connector.
Common potential equalisation connection and emergency switch.
Maximum total power: 44 kW.

2. Cooling water

Closed system. Fore run: 10 bar/30°C (a pressure reducer may be used in special cases); return run: 1.8 bar/42° C.
2 hose connection nipples 10 mm Æ NW each.

Please note: Cooling water has VE-quality (10 µS) - therefore stainless steel fittings have to be used.
QH2O ~12-15 l/min

3. Compressed air

4 FESTO couplings with automatically acting shut-off, 8.5 bar, dried.

4. GHe recycling

One coupling 20 mm Æ NW and associated counter in the supplies frame on the hall.

5. Exhaust line

20 mm Æ NW hose connection nipples for non-toxic and non-explosive gases, capacity ca. 8-10 m3/h.

6. Hazardous gases exhaust line

For toxic and explosive gases and gas mixtures, 25 mm Æ NW hose connection nipples, exhaust capacity ca. 11-15 m3 (only available if supplies frame in the hall is equipped with a safety gas cabinet).

7. Mobile safety gas cabinets

For the use of:

  • lecture bottles with PxV ³ 20 at the experiment;
  • steel bottles for technical gases (e.g. 10 l/200 bar).

8. Two movable GHe counters

In cases where more than one user consuming LHe is connected to one fixed counter.

9. LN2

35 x 100 l Dewars and 4 x 150 l Dewars, distributed over the hall. More Information

10. LHe

On demand.

11. Turbo-Molecular-Drag pumping stations

14 Pfeiffer TSH 064/TSH 071 stations (pumping speed 33 l/s, ultimate pressure 10-9 bar) are available on a short-term loan basis.
