Environmental Stress Cracking of Thermoplastic Polyimide Insulated Wires

Polyimide is often the first choice to insulate instrumentation and magnet wires working under demanding environmental and operating conditions since it shows good mechanical properties at low temperatures and high radiation resistance. Nevertheless, we have recently discovered that thermoplastic polyimide (TPI) insulated wires may suffer an accelerated brittle failure from a combination of environmental and mechanical stress, summarized as environmental stress cracking (ESC).

The ATLAS fast tracker processor design
/ Volpi, Guido (INFN, Pisa ; Pisa U.) ; Adelman, Jahred (Yale U.) ; Albicocco, Pietro (Frascati) ; Alison, John (Pennsylvania U.) ; Ancu, Lucian Stefan (Geneva U.) ; Anderson, James (JIVE, Dwingeloo) ; Andari, Nansi (Tours U., CNRS) ; Andreani, Alessandro (INFN, Milan Bicocca ; Milan Bicocca U.) ; Andreazza, Attilio (INFN, Milan ; Milan U.) ; Annovi, Alberto (INFN, Pisa) et al.
The extended use of tracking information at the trigger level in the LHC is crucial for the trigger and data acquisition (TDAQ) system to fulfill its task. Precise and fast tracking is important to identify specific decay products of the Higgs boson or new phenomena, as well as to distinguish the contributions coming from the many collisions that occur at every bunch crossing.

The associative memory (AM) system is a computing device made of hundreds of AM ASICs chips designed to perform “pattern matching” at very high speed. Since each AM chip stores a data base of 130000 pre-calculated patterns and large numbers of chips can be easily assembled together, it is possible to produce huge AM banks. [...]
