Application for LCGT membership Prof. Riccardo DeSalvo University of Sannio Benevento, Italy

The University of Sannio University of Sannio group (prof. I. Pinto) has a history of collaboration with TAMA Later joined LSC, working on Data analysis and on mirror development (in collaboration with me)

The University of Sannio (2) With the start of LCGT the Sannio group is re-organizing to support LCGT Initially with mirror coating, mechanics, controls, eventually with data analysis The group will formally apply in the next few months The mechanics contribution is urgent => Individual pre-application to LCGT

What about me, and why LCGT I am a physicist loves to work with new technologies and do precision engineering I have a string of achievements in many areas of experimental physics I have already contributed with TAMA-SAS I like to work with, and train young scientists It would be a great privilege to contribute my work to make LCGT a success

Why join LCGT ? It was great working in Japan for TAMA and with Kuraray and other Japanese projects. LCGT selected SAS, one of my best concepts, of which I am very proud LCGT is the first underground GW detector, leading to the 3 rd generation, and it is a great new challenge ! !

What can I do for LCGT I spent 15 years perfecting the SAS technique and understanding the behavior of the necessary materials I’d like to put this effort to good use My most important contribution to LCGT would therefore be to develop and implement its SAS seismic isolation, working with Takahashi

What else can I do for LCGT I have : – Experience in Vacuum techniques – Experience with mirror and coating development (Pinto, Mexican hat interferometer) – Considerable experience with underground operations. I am the son of a miner, I worked extensively in tunnels in CERN and Fermilab, and most recently in DUSEL and fully appreciate the problems involved.

What can I bring to LCGT I worked in Virgo and LIGO as they developed I learned what was relevant and what’s not I can contribute this experience I started studying the problems of third generation observatories (DUSEL-ET) – e.g. the xylophone concept I can help LCGT to become the 3 rd generation pathfinder

What else can I bring to LCGT I enjoy collaborations and I have always worked with a wide variety of scientists Hearing that I may join LCGT, a number of scientists from Italy, Netherlands and the US have already expressed a desire to collaborate with me in LCGT

What can I do besides LCGT I have R&D ideas about improving material performance both in springs and coatings During my life I dealt with ~ 100 students and young scientists, some Japanese I can suggest student thesis projects and mentor them

Conclusion It would be a great privilege for me to be accepted into the LCGT team

My academic and research history 1979 Atomic spectroscopy master thesis at University of Pisa on super-radiant pulses in Cs (building lasers, tests on laser assisted gene splitting) 1980 Apply for graduate studies – Accepted to Ecole Normale Superieure de Paris – Instead, I was directly offered an unsolicited research fellowship (postdoc) at CERN (I became the youngest postdoc at CERN)

CERN postdoc ( ) Built lasers for calibration of drift chambers In charge of the beam detectors of the SPS experimental halls (~ 1000 photomultipliers) Developed drift chambers for luminosity monitor and p-pbar cross section measurement at SPS collider I built the apparatus for Jim Cronin’s lifetime experiment

Cornell postdoc/staff scientist ( ) Design/build large collider drift chamber Design/build elastic scattering experiment at Fermilab Design/build CESR Beryllium pipe/vertex drift chamber collision region Contributed tracker designs for SSC and CEBAF

CERN staff scientist ( ) Spaghetti calorimetry development program – Development of scintillating/wavelength shifting fibers with Kiowa-gas/Kuraray Invention/development of Hybrid Photo Diode – (Work also with Hamamatsu) Quartz fiber calorimetry development Work on avalanche photo diodes – It explains why CMS e.m. calorimeter has false readings

Switch to Gravitational Waves (1994) I returned to Italy I chose to work at Virgo on the fascinating and challenging field of Gravitational Wave Detection

Virgo INFN scientist ( ) Design/Prototype the superattenuators – Introduce maraging for springs – Eliminate shear clamps Design/Prototype accelerometers Some interest in vacuum pipe & baffle design

LIGO Caltech scientist ( ) Develop GAS filters and SAS structure Design Hongo-SAS and TAMA-SAS (Takamori) Design/Build/test HAM-SAS Provide design for AEI-SAS and NIKHEF-SAS for Virgo

LIGO Caltech scientist ( ) Mesa beam experiment to reduce mirror thermal noise Design of optimized coating mirrors (Pinto) Directional radiative cooling (Kawamura-kun)

LIGO Caltech scientist ( ) Identified problem with mechanical noise from SOC of dislocations Work on glassy metal springs/flexures Work on creep Development of techniques for third generation, experience in underground GW observatories, NN subtraction,... Serve on Vacuum Review board

Publications I have written or contributed to 270+ publications, most on refereed scientific journals I have two patents I am editing a book on Optical coatings
