FlexARPES

The FlexMod System concept is a modular, yet flexible system design concept, combining several years of experience in system building with the demands of new scientific and analytical tasks. Within the FlexMod family, analysis systems are interoperable by following relevant design standards but can be modified to fit individual scientific tasks.

The SPECS FlexARPES system is a fully equipped UHV analysis system for modern surface analysis including ARPES and XPS. All systems are design and manufactured at the SPECS headquarter in Berlin. A special engineering group personally accompanies the system process from the order placing until the final acceptance. Our engineers are dedicated to highest quality and usability of the system during design, testing and setup on site. Once the system is in full operation a professional service team in our HQ and our worldwide branch offices takes care of a smooth and stable operation.

The SPECS lab ARPES system comes with the ASTRAIOS 190 momentum mapping analyzer series in combination with a ultra low temperature manipulator, sophisticated sample handling and a monochromatic small spot UV and X-ray source. The analysis module is based on a special µ-metal chamber optimized for low kinetic energy analysis. A dedicated surface science preparation module with all necessary techniques (surface cleaning, LEED, deposition, sample storage) is included as well as a fast entry loadlock.

The FlexMod series offers several configuration, such as different pumping schemes, several analysis chambers, including dual level and ultra low magnetic field solutions for laser ARPES and adjustable frame modifications for laser and synchrotron endstations. 

The typical vacuum achieved in SPECS systems is better than 2 x 10^-10 mbar achieved during assembly at SPECS. A final end pressure in the 10^-11 mbar range is achievable. The standard pumping configuration consist of and ion getter pump (IGP), a titan sublimation pump (TSP) and a turbo molecular pump (TMP) with connecting to a roughing vacuum. Different pumping configurations are available on request including larger pumping schemes and also NEG pumps.

All systems are equipped with a rigid frame and included bake-out tents with automated heating systems. An electronics cabinet hosts all relevant electronics, a main power supply and a TCP/IP based communication platform for the control units.

The FlexMod family features modular systems based on established design. The specifications may vary with the final configuration of the full system. The project plan includes a detailed technical clarification.
