| Q1: |
How long does the cool down take? |
| A1: |
The typical cooldown time of a standard microscope insert from 300 K to 5 K takes < 1 hour (with the system at base temperature).
The initial cooldown of the attoDRY1000 from room temperature to 4 K is < 5 hours (< 10 hours) without magnet (incl. a 9 T magnet).
|
| Q2: |
What is the maximum magnetic field at 4 K and 300 K? |
| A2: |
For the standard 9 T magnet, attocube guarantees the full field at 4 K, while at 300 K, 6 T can be reached. (Other magnet options (higher / lower fields, 2D/3D vector magnets) available on request.)
|
| Q3: |
What kind of pumping systems are required for the installation, cooling down and warming up? |
| A3: |
A suitable pumping station incl. turbo pump is available as an optional item in the basic package to evacuate the sample tube (including the necessary KF parts) as well as the dewar volume / insulating vacuum spaces.
The optional automation upgrade kit (turnkey operation of the T and B control incl. automated gas handling) already includes all necessary pumps and KF fittings. |
| Q4: |
What is the available sample space? |
| A4: |
The available sample space (ID) is 49.7 mm, compatible with all standard microscope and probe station inserts offered by attocube systems.
|
| Q5: |
What is the advantage of having a top loading cryostat system?
|
| A5: |
The main benefit of a top loading system is its ease of use and the fast sample turnaround times.
|
| Q6: |
What components are included with the system? |
| A6: |
Base package: Top-loading, low vibration closed-cycle cryostat with 49.7 mm sample space inside inner vacuum tube, compressor & He flex lines (10 m; longer lines available upon request), vibration isolated sample tube (OD = 2”, ID = 49.7 mm)
Magnet upgrade: 9 T magnet (other field strengths and 2D/3D vector magnets available on request), suitable bipolar magnet power supply.
Optional items:
* dual channel temperature controller, incl. test and all necessary wiring to cryostat
* transport measurement insert incl. 12 wires as twisted pairs, 2 coaxial lines, and service lines for heater and calibrated T sensor, connection cables from insert to break out panels

| Q7: |
What utilities are required (power, water cooling) to run the attoDRY1000? |
| A7: |
For operation of the pulse tube compressor, cooling water with a minimum flow of 9 LPM (2.3 GPM) @ 27°C (80°F) maximum temperature and 3-phase 380/420 VAC @50Hz or 3-phase 460VAC @60Hz power is required; For the microscope systems, regular single phase mains power is sufficient.
|
| Q8: |
Can the attoDRY1000 be connected firmly to a floating optical table? |
| A8: |
Yes. As a standard option, the attoDRY1000 can also be installed such that the sample tube is firmly connected to an optical table, which defines a fixed reference position between the optical setup on the table and the sample inside the cryostat. Complex free-beam based optical setups can thus be seamlessly interfaced with the cryogenic sample environment and high magnetic fields.
|
| Q9: |
Which scanning probe microscope inserts are compatible with the attoDRY1000?
|
| A9: |
Confocal microscopes, cantilever based atomic and magnetic force microscopes, scanning Hall probe microscopes, confocal Raman microscopes and cryogenic probe stations are compatible with the attoDRY1000.
