Our group has been developing x-ray microcalorimeters consisting of neutron transmutation doped (NTD) germanium
thermistors attached to superconducting tin absorbers. We discuss the performance of single pixel x-ray detectors, and describe
an array technology. In this paper we describe the read-out circuit that allows us to measure fast signals in our detectors as
this will be important in understanding the primary cause of resolution broadening. We describe briefly a multiplexing scheme
that allows a number of different calorimeters to be read out using a single JFET. We list the possible causes of broadening
and give a description of the experiment which best demonstrates the cause of the primary broadening source. We mention
our strategy for finding a suitable solution to this problem and describe briefly a technology for building arrays of these
calorimeters.

We have developed a compact fieldable optically-deflected streak camera first reported in the 20th HSPP Congress. Using
a triggerable galvanometer that scans the optical signal, the imaging and streaking function is an all-optical process without
incurring any photon-electron-photon conversion or photoelectronic deflection. As such, the achievable imaging quality is
limited mainly only by optical design, rather than by multiple conversions of signal carrier and high voltage electron-optics
effect. All core elements of the camera are packaged into a 12x24 footprint box, a size similar to that of a conventional
electronic streak camera. At LLNL’s (Lawrence Livermore National Laboratory) Site-300 Test Site, we have conducted a
Fabry-Perot interferometer measurement of fast object velocity using this all-optical camera side-by-side with an intensified
electronic streak camera. These two cameras are configured as two independent instruments for recording synchronously each
branch of the 50/50 splits from one incoming signal.

In this mode the microscope is designed to emulate the illumination and imaging characteristics of a stepper to enable
rapid evaluation of mask defects without the need for a resist exposure step. The main uses of the microscope in this mode
would be: review of multilayer and pattern defects to determine their printability; defect review following a repair process to
assess the success of the operation; investigation of the effects of illumination and NA on the printed image; process window
analysis of defects and other mask features, and characterizing defects on both patterned and unpatterned masks (i.e. blanks).
An essential characteristic of operation in this mode is that the illumination and imaging conditions should emulate that of a
production stepper system.

Application of Matrix-Assisted Laser Desorption/ionization to On-line Aerosol Time-of-Flight Mass Spectrometry

Matrix-assisted laser desorption/ionization (MALDI) mass spectra were obtained from a single biological aerosol
particles using an aerosol time-of-flight mass spectrometer (ATOFMS). The inlet to the ATOFMS was coupled with an
evaporation/condensation flow cell that allowed the aerosol to be coated with matrix material as the sampled stream entered
the spectrometer. Mass spectra were generated from aerosol composed either of gramicidin S or erythromycin, two small
