  Microwave Kinetic Inductance Detectors (MKIDs) are beginning to become more
prominent in astronomical instrumentation, due to their sensitivity, low noise,
high pixel count for superconducting detectors, and inherent energy and time
resolving capability. The Kinetic Inductance Detector Spectrometer (KIDSpec)
will take advantage of these features, KIDSpec is a medium resolution MKID
spectrograph for the optical/near infrared. KIDSpec will contribute to many
science areas particularly those involving short and/or faint observations.
When short period binary systems are found, typical CCD detectors will struggle
to characterise these systems due to the very short exposures required, causing
errors as large as the estimated parameter itself. The KIDSpec Simulator (KSIM)
has been developed to investigate how much KIDSpec could improve on this.
KIDSpec was simulated on an ELT class telescope to find the extent of its
potential, and it was found that KIDSpec could observe a $m_{V}\approx{24}$
with an SNR of 5 for a 10s exposure at 1420 spectral resolution. This would
mean that KIDSpec on an ELT class telescope could spectroscopically follow up
on any LSST photometric discoveries of LISA verification sources.
