Access To Data

The CMS Zero Degree Calorimeters, ZDCs, will measure photons and neutrons emitted with |η| ≥ 8.6 from Pb + Pb , p + Pb and p + p collisions at [Formula: see text], 8.8 and 14 TeV respectively. The calorimeter consists of an electromagnetic part segmented in the horizontal direction and an hadronic part segmented into four units in depth. In addition CMS will have access to data from a segmented shower maximum detector being built for luminosity measurements. We will present detailed results from tests beam measurements taken at the CERN SPS. These data will be used to extrapolate the utility of the ZDCs to measure photons, and possibly π0 s in p + p and ultra-peripheral heavy-ion collisions. Data from the hadronic section can be used to estimate the number of participants in heavy ion-collisions. In addition we will discuss plans to use the detector to measure the reaction plane, thereby extending the sensitivity of the central detectors in CMS.

Simulation Results

It is proposed to replace existing Zero Degree Calorimeter of the BM@N setup at the Nuclotron (JINR) by a new forward hadron calorimeter for the measurement of the collision centrality and reaction plane orientation in heavy ions experiments. This calorimeter with transverse and longitudinal segmentation will be assembled from modules presently constructed for FHCal MPD and PSD CBM. The proposed design of the new calorimeter, simulation results for centrality and reaction plane determination by the new calorimeter, as well as radiation doses in the calorimeter simulated by FLUKA are discussed. The performance of hadron calorimeter supermodule studied at CERN is shown.

This essay examines certain intersections between writing and extinction through an eco-deconstructive account of the psychoanalysis of water. Jacques Derrida has often drawn attention to the interplay between the sound ‘O,’ and ‘eau,’ in Maurice Blanchot's own proper name, as well as in his novels, récits and theoretical works; both the zero-degree of organic excitation towards which the death drive aims and the question of water. Sandor Ferenczi's notion of thalassal regression suggests that the desire to return to the tranquility of the maternal womb parallels a response to a traumatic prehistoric extinction event undergone by organic life once forced to abandon its aquatic existence. Through Gaston Bachelard's Water and Dreams: An Essay on the Imagination of Matter, however, one can double the imaginary of water along the axes of a personal death organic life defers and delays, and an impersonal extinction it cannot. Derrida's unpublished 1977 seminar on Blanchot's 1941 novel Thomas the Obscure, however, allows us to imagine an exteriority to extinction, the possibility
