The main goal of the NA62 experiment at CERN is
to measure the branching ratio of the ultra-rare K+ → π+ν¯ν decay
with 10% accuracy. NA62 will use a 750MHz high-energy
un-separated charged hadron beam, with kaons corresponding
to ∼ 6% of the beam, and a kaon decay-in-flight technique. The
positive identification of kaons is performed with a differential
Cherenkov detector (CEDAR), filled with Nitrogen gas and placed
in the incoming beam. To stand the kaon rate (45MHz average)
and meet the performances required in NA62, the Cherenkov
detector has been upgraded (KTAG) with new photon detectors,
readout, mechanics and cooling systems. The KTAG provides a
fast identification of kaons with an efficiency of at least 95%
and precise time information with a resolution below 100 ps. A
half-equipped KTAG detector has been commissioned during a
technical run at CERN in 2012, while the fully equipped detector,
its readout and front-end have been commissioned during a pilot
run at CERN in October 2014. The measured time resolution
and efficiency are within the required performances.

simulazione ASN
Il report seguente simula gli indicatori relativi alla propria produzione scientifica in relazione alle soglie ASN 2023-2025 del proprio SC/SSD. Si ricorda che il superamento dei valori soglia (almeno 2 su 3) è requisito necessario ma non sufficiente al conseguimento dell'abilitazione. La simulazione si basa sui dati IRIS e sugli indicatori bibliometrici alla data indicata e non tiene conto di eventuali periodi di congedo obbligatorio, che in sede di domanda ASN danno diritto a incrementi percentuali dei valori. La simulazione può differire dall'esito di un’eventuale domanda ASN sia per errori di catalogazione e/o dati mancanti in IRIS, sia per la variabilità dei dati bibliometrici nel tempo. Si consideri che Anvur calcola i valori degli indicatori all'ultima data utile per la presentazione delle domande.
La presente simulazione è stata realizzata sulla base delle specifiche raccolte sul tavolo ER del Focus Group IRIS coordinato dall’Università di Modena e Reggio Emilia e delle regole riportate nel DM 589/2018 e allegata Tabella A. Cineca, l’Università di Modena e Reggio Emilia e il Focus Group IRIS non si assumono alcuna responsabilità in merito all’uso che il diretto interessato o terzi faranno della simulazione. Si specifica inoltre che la simulazione contiene calcoli effettuati con dati e algoritmi di pubblico dominio e deve quindi essere considerata come un mero ausilio al calcolo svolgibile manualmente o con strumenti equivalenti.
