TIFUUN is a portable 90-360 GHz integral field spectrometer with up to 18,000 detectors and R up to 1000, optimized for CII line intensity mapping at z~6 on the ASTE telescope.
Optimizing electron-beam lithography via smaller beam step size and avoiding main-field stitching reduces random and systematic frequency scatter four-fold in superconducting microstrip resonators.
Reviews how cross-correlating SKAO 21-cm LIM with other lines like [CII], CO, and Ly-alpha can mitigate systematics, enhance sensitivity, and disentangle cosmological from astrophysical parameters.
