Coherent beam-beam experiments and implications for head-on compensation
S. White, M. Blaskiewicz, W. Fischer +1
In polarized proton operation in the Relativistic Heavy Ion Collider (RHIC) coherent beam-beam modes are routinely observed with beam transfer function measurements. These modes ca…
Operation of the 56 MHz Superconducting RF Cavity in RHIC with Higher Order Mode Damper
Q. Wu, S. Belomestnykh, I. Ben-Zvi +6
A 56 MHz superconducting RF cavity was designed and installed in the Relativistic Heavy Ion Collider (RHIC). It is the first superconducting quarter wave resonator (QWR) operating…
Measurement of the total cross section of uranium-uranium collisions at GeV
W. Fischer, A. J. Baltz, M. Blaskiewicz +7
Heavy ion cross sections totaling several hundred barns have been calculated previously for the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC). These to…
Schottky Signal Modification as a Diagnostic Tool for Coherent Electron Cooling
W. F. Bergan, M. Blaskiewicz, G. Stupakov
Coherent electron cooling is a promising technique to cool high-intensity hadron bunches by imprinting the noise in the hadron beam on a beam of electrons, amplifying the electron…
Anomalous skin effect study of superconducting film
Binping Xiao, M. Blaskiewicz, T. Xin
The field distribution inside the superconducting radiofrequency (SRF) film with different mean free path is studied using niobium (Nb) as an example. The surface resistance of cle…
A Storage Ring Experiment to Detect a Proton Electric Dipole Moment
V. Anastassopoulos, S. Andrianov, R. Baartman +88
A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of cm by using polarized "magic" momentum ~GeV/c pr…
Recent RHIC in-situ coating technology developments
A. Hershcovitch, M. Blaskiewicz, J. M. Brennan +16
To rectify the problems of electron clouds observed in RHIC and unacceptable ohmic heating for superconducting magnets that can limit future machine upgrades, we started developing…
Study of the anomalous skin effect of normal conducting film
Binping Xiao, M. Blaskiewicz, T. Xin
For the radiofrequency (RF) applications of normal conducting film with large mean free path at high frequency and low temperature, the anomalous skin effect differs considerably f…
Status of head-on beam-beam compensation in RHIC
W. Fischer, Z. Altinbas, M. Anerella +34
In polarized proton operation, the performance of the Relativistic Heavy Ion Collider (RHIC) is limited by the head-on beam-beam effect. To overcome this limitation, two electron l…
Time evolution of the luminosity of colliding heavy-ion beams in BNL Relativistic Heavy Ion Collider and CERN Large Hadron Collider
R. Bruce, M. Blaskiewicz, W. Fischer +1
We have studied the time evolution of the heavy ion luminosity and bunch intensities in the Relativistic Heavy Ion Collider (RHIC), at BNL, and in the Large Hadron Collider (LHC),…
