“…The experiment was performed at the HIRFL-CSR (Cooler-Storage Ring at the Heavy Ion Research Facility in Lanzhou) [27]. The CSRe was operated in the isochronous mode to measure masses of short-lived T z = −1/2 [39] and T z = −3/2 [40] nuclei.…”

“…Owing to dedicated time-of-flight detectors, IMS has a very high detection efficiency and is sensitive to single stored ions [26]. Furthermore, experimental cooler storage ring (CSRe) tuned into the IMS ion-optical mode can simultaneously store ions with a relative momentum acceptance ∆P/P of ∼ 0.2% [27]. The latter is important in view of the wide velocity distribution of projectile fragments.…”

Isochronous mass spectrometry was applied to measure isomeric yield ratios of fragmentation reaction products. This approach is complementary to conventional γ-ray spectroscopy in particular for measuring yield ratios for long-lived isomeric states. Isomeric yield ratios for the high-spin I = 19/2h states in the mirror nuclei 53 Fe and 53 Co are measured to study angular momentum population following the projectile fragmentation of 78 Kr at energies of ∼ 480 A MeV on a beryllium target. The 19/2 state isomeric ratios of 53 Fe produced from different projectiles in literature have also been extracted as a function of mass number difference between projectile and fragment (mass loss). The results are compared to ABRABLA07 model calculations. The isomeric ratios of 53 Fe produced using different projectiles suggest that the theory underestimates not only the previously reported dependence on the spin but also the dependence on the mass loss.

VHEeP: a very high energy electron–proton collider

Based on current CERN infrastructure, an electron-proton collider is proposed at a centre-of-mass energy of about 9 TeV. A 7 TeV LHC bunch is used as the proton driver to create a plasma wakefield which then accelerates electrons to 3 TeV, these then colliding with the other 7 TeV LHC proton beam. Although of very high energy, the collider has a modest projected integrated luminosity of 10-100 pb −1 . For such a collider, with a centre-of-mass energy 30 times greater than HERA, parton momentum fractions, x, down to about 10 −8 are accessible for photon virtualities, Q 2 , of 1 GeV 2 . The energy dependence of hadronic cross sections at high energies, such as the total photon-proton cross section, which has synergy with cosmic-ray physics, can be measured and QCD and the structure of matter better understood in a region where the effects are completely unknown. Searches at high Q 2 for physics beyond the Standard Model will be possible, in particular the significantly increased sensitivity to the production of leptoquarks. These and other physics highlights of a very high energy electronproton collider are outlined.

“…The inhomogeneity, or wakefield, is a wave in the plasma electron density that propagates at the group velocity of the pulse (or velocity of the bunch) and whose longitudinal electric field is several orders of magnitude greater than that achievable within radio-frequency cavities. Driven mainly by the spectacular success of a number of landmark experiments and simulations [9][10][11][12] approximately a decade ago, plasma-based wakefield acceleration [13] is now recognised as a vital concept for the next generation of terrestrial particle accelerators [14,15].…”

Axionic suppression of plasma wakefield acceleration

Contemporary attempts to explain the existence of ultra-high energy cosmic rays using plasma-based wakefield acceleration deliberately avoid non-Standard Model particle physics. However, such proposals exploit some of the most extreme environments in the Universe and it is conceivable that hypothetical particles outside the Standard Model have significant implications for the effectiveness of the acceleration process. Axions solve the strong CP problem and provide one of the most important candidates for Cold Dark Matter, and their potential significance in the present context should not be overlooked. Our analysis of the field equations describing a plasma augmented with axions uncovers a dramatic axion-induced suppression of the energy gained by a test particle in the wakefield driven by a particle bunch, or an intense pulse of electromagnetic radiation, propagating at ultra-relativistic speeds within the strongest magnetic fields in the Universe.
