“…This is achieved with an individual front-end channel unit consisting of a small mezzanine printed circuit board (PCB) called a "MENU". The principal MENU components are an ASIC named the Charge Integration Encoder (abbreviated "QIE") [31], a commercial flash analog-to-digital converter ("FADC"), and a data buffer. Sixteen MENUs reside on a VME type-6U PCB (called a "MINDER"), with four MIN-DERs required for each fully used M64 PMT.…”

The Main Injector Neutrino Oscillation Search (MINOS) experiment uses an acceleratorproduced neutrino beam to perform precision measurements of the neutrino oscillation parameters in the "atmospheric neutrino" sector associated with muon neutrino disappearance. This long-baseline experiment measures neutrino interactions in Fermilab's NuMI neutrino beam with a near detector at Fermilab and again 735 km downstream with a far detector in the Soudan Underground Laboratory in northern Minnesota. The two detectors are magnetized steel-scintillator tracking calorimeters. They are designed to be as similar as possible in order to ensure that differences in detector response have minimal impact on the comparisons of event rates, energy spectra and topologies that are essential to MINOS measurements of oscillation parameters. The design, construction, calibration and performance of the far and near detectors are described in this paper.

A circuit has been designed@ digitizing PMTsignals over 0 wide dynamic range (17~18 bits) with 8 bits of res&tion at rafes up to 53 MHz. Outpuffroorn *he circuit is in afloatingpointformnt with a 4 bit exponent arid on 8 bit mantissa. The heart of the circuit ir 0jW CuYtom integrated circuit catted the Q,E (Charge integrator and Encoder). The design of the QIE and o.wociated circuitry reported here permits operation over a 17 bit dynamic range.

“…Moreover, additional groups at Argonne National Lab and at the Fermi National Accelerator Lab are using the SMQIE in calorimeter wedge tests in anticipation of the start of Run II. Figure 5 shows the output of the FADC as a function of fast charge input 1 . The ration of the slope (FADC output vs. charge) of a range to the slope of the next higher range should ideally be two.…”

The Technical Design Report for the CDF II Detector calls for the development of an imbedded two-dimensional position sensitive detector sandwiched inside the electromagnetic calorimeter and placed at the shower maximum. The purpose of this detector is to aid in the identification of electrons and photons, to separate photons from π 0 s, and to help identify electromagnetic showers. This detector is called the Shower Max.In order to achieve CDF's goals for resolution, timing, power and economy, as well as to fit into the available space, a full-custom integrated circuit was required for the project -the SMQIE.The SMQIE has been fabricated in a 1.2µm CMOS process using vertical NPN transistors in critical areas. It operates without deadtime. Its QIEs have eight ranges and an overall dynamic range of 13 bits. Its FADCs have a 5-bit resolution with a nominal LSB of 31.25 mV. Its Level 1 Trigger delays are 42 beam crossings or approximately 5.5 µs. Its data buffers hold up to four events, each of which can consist of four time slices. Finally, the chip accepts a maximum input charge up to 150 pC with a minimum resolution of 15 fC.
