	Measurements in the CERN Proton Synchrotron showed that achieving the required accuracy for the emittance characterisation of high brightness beams is challenging. Some of the present limits can be related to systematic errors in the wire scanner calibration or, for the horizontal emittance determination, in the assumptions adopted while deconvoluting the contribution of the longitudinal plane from the measured transverse profile. We present in this paper the results of a beam-based test of the wire scanner calibration and of a general numerical deconvolution algorithm to compute the betatronic profile starting from the measured ones. In addition to the bunch train average emittance, a bunch-by-bunch transverse emittance measurement would increase the potential to understand, optimise and monitor the beam performance. In 2015 the first PS bunch-by-bunch measurement chain was setup. The results are reported and discussed.

	In the frame of the LIU (LHC Injectors Upgrade) project, the CERN PS Booster is going to be renovated to host a new H⁻ charge-exchange injection from the Linac4. One important feature of the new injection scheme is the possibility to tailor a wide range of 3D emittances for CERN's different users in an intensity span in the order of 5·10⁹ to 1.6·10¹³ protons per PSB ring. This paper gives an overview of 3D multi-turn injection techniques, focusing on the future LHC beams, which aim at reaching high brightness, and on highest intensity beams (ISOLDE), where losses are the main concern. Complete RF capture simulations and transverse injection maps, including space charge effects, are presented and also intended to be used during the commissioning with Linac4.

Measurements in the CERN Proton Synchrotron showed that achieving the required accuracy for the emittance characterisation of high brightness beams is challenging.

In the frame of the LIU (LHC Injectors Upgrade) project, the CERN PS Booster is going to be renovated to host a new H⁻ charge-exchange injection from the Linac4. One important feature of the new injection scheme is the possibility to tailor a wide range of 3D emittances for CERN's different users in an intensity span in the order of 5·10⁹ to 1.6·10¹³ protons per PSB ring. This paper gives an overview of 3D multi-turn injection techniques, focusing on the future LHC beams, which aim at reaching high brightness, and on highest intensity beams (ISOLDE), where losses are the main concern. Complete RF capture simulations and transverse injection maps, including space charge effects, are presented and also intended to be used during the commissioning with Linac4.
