Sample Environment

ZEBRA is operated in two geometrical modes:

• 4-circle equatorial geometry (γ = 0^o)
• tilting geometry (-14.5^o< γ <15^o) 

ZEBRA has two exchangeable detector units:

• turnable area and pointdetector (in operation)
• point detector with analyzer unit (available mid 2017) for low background

• 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

• 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)

• optical camera for centering of samples in 4-circle geometry (Eulerian cradle) at room temperature
• neutron camera for sample alignment in sample environments 

• 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
