The E2 hall is a dual-use room in which experiments could be placed on the low-energy gamma beam line while part of the space is reserved for high energy accelerating structures. On the low-energy beam line, there are designated locations for experimental setups and diagnostics stations. Two experiments foreseen for E2 hall are: the ELIADE array for Nuclear Resonance Fluorescence studies and the Industrial Applications station for CT scanning and isotope identification.
Detectors
ELIADE
Description
The ELIADE (ELI-NP Array of DEtectors) is composed of 8 segmented clover HPGe detectors and additional 4 LaBr3 detectors. The detectors are located on two rings, one at 90 degrees and the other at 135 degrees with respect to the beam axis. The angle of the detectors in the first ring can be varied with 4 degrees around the nominal working position. [Romanian Reports in Physics, Vol. 68, Supplement, P. S483–S538, 2016]

ELI-BIC
Description
The ELI-BIC (Bragg Ionization Chamber) is an assembly of four chambers, each of which contains one high-efficient double-sided Frisch-grid ionization chamber for the detection of binary fission fragments together with eight ∆E-E telescopes to measure light charged particles. Each telescope consists of an ionization chamber and a double-sided silicon strip detector (DSSD) to determine energy loss and remaining energy, respectively. As counting gas, P-10 (90% argon, 10% methane) at around 1 bar will be used. As purpose of this detector array the measurement of fission fragment properties as well as ternary fission probabilities can be mentioned.

ELISSA
Type
The Extreme Light Infrastructure Silicon Strip Array (ELISSA) will consist of 3 rings of 12 X 3 position-sensitive detectors produced by Micron Semiconductor Ltd., in a barrel like configuration. To extend the angular
coverage an end cap detectors assembly consisting of four QQQ3 segmented detectors by Micron Semiconductor Ltd will be used. So that, the final design of ELISSA will ensure very good resolution and granularity in a compact detection system covering almost 80% of the total angular range.

ELITHGEM
Description
This array consists of 12 detectors of THGEM (THick Gas Electron Multiplier) type, which offer position sensitivity as well as high gain. The entire detector covers a solid angle of around 80% of 4π and each THGEM unit, together with a segmented readout electrode, provides a true pixelated radiation localization with an angular resolution of about 5°. The array is contained inside a gas chamber, filled with isobutane gas at a pressure of around 5 mbar. ELITHGEM is dedicated e.g. to the measurement of cross sections and fission fragment angular distributions.

ETPC
Description
The ELI Time Projection Chamber (ELITPC) is a gaseous detector in which the gas acts at the same time as a target for the nuclear reaction and detection medium. The detector will be used to investigate the multi alpha-particle decay of light nuclei such as 12C and 16O and the cross section of photo-dissociation reactions (γ,p) or (γ,α).
The active volume of the chamber, in which the reaction happens and the decay products are detected, will have a length of 35 cm and a square cross-section of 20 cm × 20 cm, centred around the beam axis with a window for the gamma beam and another on the side for an alpha source.
The multiplication of the drifting electrons will be achieved by a sequence of 35 cm × 20 cm Gas Electron Multiplier (GEM) foils. The charge will be read by a u-v-w readout which is mounted on a circuit board using multi-layering board technology, as shown, and it is formed by three layers of (u-v-w) grids crossed at 60°.
Combination of the 2D position in the collection plane with time information will allow the 3D reconstruction of the reaction products. The 3D reconstruction of events will also allow us to identify reactions in which more than two particles are involved, like 12C(γ,3α), or when more events (including background) happen within a short time-window of the information collection.

IGISOL
Description
The ELI-IGISOL facility will produce radioactive ion beams (RIBs) via photofission in a stack of actinide targets placed at the center of a gas cell. This Cryogenic Stopping Cell (CSC) will operate with helium at around 75K and will employ diverse DC and RF electric fields to thermalize and drift out quickly the fission fragments. A Radio-Frequency Quadrupole (RFQ) will form the RIBs by cooling, bunching and mass filtering these fragments. The exotic neutron-rich component of the RIBs will be selected by a Multiple Reflection Time-of-Flight (MR-ToF) mass spectrometer with high resolving power. Finally, the selected rare and exotic nuclei will be analyzed by a beta-decay tape station and a collinear laser spectroscopy station. This project is a collaboration between ELI-NP and several international institutes with broad experience in this field. Most notably, the expertise developed by the GSI institute and the Giessen University at the Ion Catcher facility will be extended in the joint development of the CSC, RFQ and MR-ToF devices, while the expertise developed at the IPN Orsay institute for measurement stations like those mentioned above will be employed in the joint development of those planned at ELI-IGISOL.
