DESTINY+ Dust Analyser (DDA) is an impact ionization TOF-MS dust analyser to be onboard the JAXA's
DESTINY+ spacecraft for Phaethon flyby exploration. DDA will reveal the bulk chemical composition of
interplanetary and interstellar dust particles and Phaethon ejecta particles. DDA can obtain TOF mass
spectra of positive ions generated by impact ionization of dust particles. This presentation gives the status
report of the development and ground calibration of DDA in 2024 to early 2025. The flight model (FM)
design of DDA is almost fixed. In the calibration test with the dust accelerator at the University of Stuttgart, mineral (e.g. olivine) and organic (e.g. perylen) particles coated with conductive materials have been successfully accelerated and impacted on the engineering model (EM) of DDA. The impact ionization
mass spectra have been archived for the future interpretation of spectra to be obtained in orbit.
