A mass spectrometer based on a 3/4 sphere electrostatic analyzer, with a radial magnetic field located 180 degrees from the entrance aperture, is to be flown on the upcoming sounding rocket project TRICE. Ion optics simulations, used to optimise the geometric factor and mass resolution, will be described. The imaging scheme is based on multiple low-resolution imaging areas, each one corresponding to a mass distribution, and each with its own low-power digital imaging electronics. The lack of postacceleration high voltage supplies, together with the simplified imaging, allow this instrument and its electronics to be kept very compact and inexpensive. The trade-off is that magnetic mass analysis at variable energies requires an electromagnet. The power of this electromagnet is kept at reasonable levels by using one compact magnetic field region for particles at multiple angles.
