Abstract: The status of the ASHIPH (Aerogel, wavelength SHIfter, and PHotomultipliers) system of the KEDR detector is described. The measurement of the quality of the particle identification with the ASHIPH counters was performed. The π/K separation is 4.5σ for the momentum Full-size image (<1 K) and 4.7σ for the momentum Full-size image (<1 K). Timing properties of the ASHIPH counter are measured. The time resolution for pions is Full-size image (<1 K), and the BBQ decay time is Full-size image (<1 K). The advantages and disadvantages of Cherenkov counters filled with aerogel crumb are discussed. The process of the mass counter production for the KEDR detector is described.
