Next generation scintillating-fiber tracker for HI mu beamline,
Fuji CRT and other tracking requirements.
The documents presented on this website are relevant
references for the SCiFi Tracker design, operation and
testing.
The content is divided into sub-sections like design, hardware,
software, testing and others.
News and Updates
November 14: The CSciFi box assembly has been upgraded with
the scintillating-fibers (SCROD is the only thing
missing).
November 7: The CSciFi box has been assembled to the point of
being SW/Firmware test ready.
November 6: The Daughter Card and Mother board has been
received and tested for short as well as mechanical
alignment.
November 4: Power board (IDL_14_42) has been Tested and works
within expected criteria.
November 3: Power board (IDL_14_42) has been assembled on the
IDL P&P line.

Hardware Reference
Documents
In this section the documents provided contain data relevant to
the hardware (schematics, PCB prints, BOMs, etc...).
Three PCB boards have been redesign: The daughter card with the
TargetX ASIC, The mother board (smaller dimensions) and a Power
board for power supply generation
The MPPC array board has been reused form the previous versions
of the Tracker. For processing and control SCROD revA4 is used
Mechanical Reference
This section provides an overview of the motivations for the
CSciFi enclosure. The enclosure needed to be light-tight and not
heavily impede through-going muons. Hence it was constructed with
1/4" 6061 aluminum alloy, using jointed wall connections, and
featured 1.5 mil 321 stainless steel foil windows directly above and
below the scintillating grid. It was assembled using black RTV
silicone at jointed edges and around panel-mount connectors to
further improve light tightness. The enclosure was bolted together
using 6-32 socket-head cap screws (304 stainless steel). The mother
board was assembled with 2 1/4" standoffs as well as aluminum
scintillator support brackets, and then inserted into the enclosure
and bolted to the bottom plate with additional 6-32 screws. The
design allows for 1/10" spacing all the way around the motherboard,
which may later be filled with a rubber molding to provide lateral
support (which would help support the motherboard whenever the
device is operated in a horizontal configuration). In anticipation
of possible CSciFi applications, the enclosure features mounting
slots for vertical, horizontal, and even suspended mounting
configurations. Half of the slots align with a standard optics bench
(1/4-20 on 1 inch grid), and the other half align with a metric
optics bench (M6 on 25mm grid).
