Field of View (FOV) Each channel shall have an array of 16 pixels each with a FOV : 20 x AF/16(horizontal x elevation) where AF is 3. 2. The combined FOV: 20 x 3. 2 (horizontal x elevation). NCKU UCB Tohoku CDR 9 Jul 2001 Array Photometer Mechanical H. Fukunishi 8

PMT Vibration Test Tube installed in AP Qualification Test Unit Date: 18/19 Dec. , 2000 Location: . ISAS (Institute of Space and Astronautical Science) Max Level: Sin Random 25 G (perp. to mounting plane), 0. 5 G (other axes) 0 d. B (perp. to mounting plane), -12 d. B (other axes). No resonance signature up to 150 Hz. The PMT survived all the trial and output signals seems normal. NCKU UCB Tohoku CDR 9 Jul 2001 Array Photometer Mechanical H. Fukunishi 9
