The report is devoted to the beam energy measurement systems which are now in operation at the BEPC-II and the VEPP-2000 colliders. After brief histrorical overview, it describes the principles of operation, interesting options, present performance and accuracy achievments of the approach.

The beam energy measurement system (BEMS) for Beijing electron positron collider (BEPCII) is introduced. It is based on the measurement of Compton back scattered photons. The relative systematic uncertainty of beam energy measurement is estimated as $2*10^{-5}$. Some upgradations for BEMS are also introduced.

Luminosity measurements at LHCb are of pivotal importance.
They have been used in about 50 LHCb publications of production cross section results.
The interaction rate at LHCb is continuously monitored by several luminosity counters
(like the number of reconstructed tracks) measuring the fraction of "empty" events,
i.e. events which fall below a chosen threshold of a given luminosity...

The precision measurement of the $\pi^0\to \gamma \gamma$ width allows to gain insights into the strong QCD dynamics. A way to achieve the precision needed (1%) in order to test Theory predictions is to study the $\pi^0$ production trough $\gamma \gamma$ fusion in the $e^+ e^- \to e^+ e^- \gamma^{\star} \gamma^{\star}\to e^+ e^- \pi^0$ reaction. The KLOE-2 experiment, currently running at...

Mu3e is a dedicated experiment for the rare lepton flavour violating decay $\mu^{+} \rightarrow e^{+}e^{-}e^{+}$. Its ultimate goal is to find or exclude this process if it occurs more than once in $10^{16}$ muon decays. This constitutes four orders of magnitude improvement with respect to the predecessor.

In the present ILC design the beam crossing angle for e+e- collisions is 14 mrad. The photon collider needs the angle about 25 mrad due to larger beam disruption angle. The solution is suggested which decreases the required crossing angle for the photon collider down to 20 mrad and allows to work in both modes of collisions without any degradation of performance.

The anomalous muon dipole magnetic moment can be measured (and calculated) with great precision thus providing insight on the Standard Model and new physics. Currently an experiment is under construction at Fermilab (USA) which is expected to measure the anomalous muon dipole magnetic moment with unprecedented precision. One of the improvements with respect to the previous experiments is...
