ZEBRA is operated in two geometrical modes:
- 4-circle equatorial geometry (γ = 0o)
- tilting geometry (-14.5o< γ <15o)
ZEBRA has two exchangeable detector units:
- turnable area and pointdetector (in operation)
- point detector with analyzer unit (available mid 2017) for low background
Equipment for 4-circle-mode
- open HUBER cradle with dedicated cryostats 4.5-300K (CCR3) and 1.6-30K (JT-CCR), small furnace (300K-800K) or optical furnace (up to 1200K, controlled gas atmosphere)
- pressure cell (20 kbar, T > 6 K)
- photocrystallography (400-800 nm, T > 50 K,100mW/cm2)
- no magnetic field possible
Equipment in tilting mode
- magnetic field: 6 and 10 Tesla vertical magnets with large out-of-plane openings, 12 Tesla vertical in MA15 (small vertical opening), and 4.5 Tesla horizontal in MA7
- cryogenics (T > ~50 mK)
- furnaces (<2000K)
Other instrument-hardware
- optical camera for centering of samples in 4-circle geometry (Eulerian cradle) at room temperature
- neutron camera for sample alignment in sample environments
Under development
- kappa goniometer for small crystals transferred from a laboratory single-crystal X-ray diffractometer (STOE Stadivari available at PSI)
- new Eulerian cradle with xyz-motorized cryostat carrier allowing diffractometric centering of samples at any temperature
