Abstract
BOMBOLO is our instrument proposal for covering a series of scientific cases, in the not-so-explored time window of tens of seconds to minutes exposures, to be installed at the SOAR observatory. BOMBOLO is a wide field imager, capable of simultaneous, synchronous and independent observations in three different bands of the near-UV and visible wavelengths. BOMBOLO will be located at one of the Bent Cassegrain focal stations. Given its length, weight and mounting limitations, we discuss the current mechanical and opto-mechanical design of the instrument, given flexures caused by a changing gravity vector. In order to validate our designs, a Monte-Carlo simulation is used to explore different observing conditions, as the starting point for static and dynamic studies of the structure using Finite Element Analysis tools. A quick update on the current state of the instrument related to the optical design and manufacturing as well as the CCD cameras is included.
