Design of continuous mHz-line clock apparatus

Using the beam source developed in Task 44 and under discussion with the QuantERA QClocks and EMPIR f17 USOQS participants UvA and UMK will design and build the apparatus suitable for replenishing atoms in continuous superradiant lasing This task involves adding the red MOT cooling stages to the beam source of Task 44 and implementing the laser systems to replenish atoms in the reservoir either the red MOT or an accumulation region in the dipole guide TUW will provide theoretical support with design of the cavity evaluation of threshold condition preliminary estimation of attainable power and linewidth of the superradiant laser for different variants of realization of the setup
