The Bose-Einstein Condensate and Cold Atom Laboratory (BECCAL) is a cold atom experiment designed for operation onboard the ISS. This multi-user facility will enable the exploration of fundamental physics with Rb and K BECs and ultra-cold atoms in microgravity, facilitating prolonged time- and ultra-low energy scales.

BECCAL must be operable without intervention for three years on the ISS. To reach that goal and match the stringent SWaP limitations, we have to fulfill strict product assurance requirements for the complex laser system. This not only involves higher cleanliness and ESD standards but also demands a meticulous integration process. To navigate this, the use of prototypes becomes imperative. In this context, the first essential integration tests, along with the adaptations made, based on the experience gained, will be presented.

This work is supported by the DLR with funds provided by the BMWK under grant number 50WP2102.
