Progress report on CHICO-X

CHICO spectrometer, designed to be an auxiliary charged-particle detector array for Gammasphere, consists of two identical hemispheres with 10 individual PPAC’s in each hemisphere. It requires modifications to be geometrically compatible to GRETA. The modified spectrometer, CHICO-X, has a smaller chamber diameter of 12.6 inches with built-in fixtures to hold PPAC’s. The new pixelated position-sensing board still is located at the original position with a flight path of 13 cm to maintain the same time and position resolutions as those of CHICO(2) but with smaller solid-angle coverage. The reduced angular coverage for θ is from 23^o to 77^o for the forward hemisphere and from 103^o to 157^o for the backward hemisphere. The φ range remains the same as that of CHICO2 covering 280^o out of 360^o. The fabrication of all the mechanical parts will be completed by September 2022 and the same schedule for the redesigned pixelated boards and transmission lines. The assembling of CHICO-X will begin in October 2022. Some detailed of those work will be presented.
